Hopefully you are right. People have this obnoxious tendency to get upset when you use the more aggressive methods to get rid of the stupid.
Dude, that's being too hopeful. We will need to make examples all over again for Westeros. At least with the Reach they will all be scared to the bone once we finish off the Court of Stars, but the rest of Westeros I am absolutely expecting nobles to overreach in ways we can't ignore.
How I'm actually seeing it is the North doesn't really send anyone who could do something stupid to SD, and everyone who
would do something stupid under other circumstances doesn't because we have a good relationship with them. Like the Umbers? By this point they'll know not to make any requests a spectacle and just send a letter. When someone does show up in court, it's because there's actually something of substance to raise a stink about it. Mormonts, same. Boltons would come and make a spectacle with our
consent because we want to make a show out of it. Who are we to begrudge a vassal their flair for the dramatic?
From the Vale, we are unlikely to see them coming to embarrass themselves, because we would have been the most thorough in weeding out the stupid during the Reconquest. Paradoxically however,I admit some skepticism to even my own assertion here. It's not as though we aren't replacing one brand of stupid entitled Andals with a bunch of tribals who's cardinal fucking sin and vice is bravado to the highest possible degree. There may not be a sense of entitlement to the spectacles they make, but certainly a need to come off as "kind of a big deal", still.
From the Stormlands... I'm expecting a bunch of dour, overly-serious and reflexively competent and minimalist envoys/nobles. When someone raises a stink, it's because someone did something Dwarven Grudge-worthy.
From the Riverlands, I expect we'll see the most issues, if we don't periodically poke our necks over and smooth over squabbles. Just every now and then looking like we're taking the place seriously should seriously cut down on most of the issues--the biggest problem the area really has is that it had an overlord not actually powerful enough to be its overlord nor well-respected or connected enough to mediate disputes. That's not a problem we'll ever have. Just showing up might actually get people cooperating where before they were at each other's throats, because no one wants to look like the embarassing middle child after all the effort we put into developing its infrastructure, handing out city charters like candy and overall raising the standing of the place head and shoulders above like three or four surrounding Kingdoms.
The Westerlands I foresee basically being fucking silent for at least a generation, and the one after that will be very quiet and respectful. It might even be characteristic of the people from there overall depending on how heavy handed we are about its administration. Which is to say very.
Dorne will sink or swim on its ability to seem like they are ahead of the game in trends and overall tying themselves and their interests together with our own. They have the biggest chance to integrate with the inner echelons of high society at our court, and fashion/other trends will show. I see high society dress code being informed greatly by Essosi and Dornish sources, not only due to climate but inclination. They will be the schmoozers and socializers, or occasionally behind scandals, but practically no one will risk giving the whole ingroup a bad name at court if they can help it, which means rapid and extreme competence at covering ones hotheaded relatives mistakes up and covering ones own ass overall. This will likely be an extensison of the "perfidious Dornish" reputation, only you'll ironically see lots of people going to them when they want to get ahead at court. Because people are hypocrites,
The Crownlands will either be full of diehard loyalists who will literally word-for-word parrot our party line, or hideous sycophants clinging to delusions of grandeur about their place in society and generally ignored by some of their own peers because they know how precarious their own position is, and how very much they need to step up their game to remain relevant at court. The northern Crownlands will generally be the most well-regarded because while a little diehard, they at least will show up and do exactly what is expected of them, and then some.
The Iron Islands could go either way, but with careful consideration and input from our end they could end up being regarded as extremely competent traders, para-military figures and explorers. Sort of the Myrish equivalent.
The Reach, I'm really less certain about, I think overall there is a sense of arrogance from the Reach which keeps them disconnected from the rest of Westeros and the world at large due to perceived superiority and general self-absorption.
