I was thinking on the subject of Sharingan copying the jutsu, and before the Uchiha massacre it makes little sense for the Uchiha not to have had jutsu instructors each generation, the way the Kurosawa have a sealmaster for each one, just because they (comparatively) easily can, and it provides high value to the clan for little effort. If one Uchiha catches a potentially-useful technique on a mission, they may have used to demonstrate it in front of a group of other Uchiha, and then they analyse what it is they do and they teach it to Leaf (unless they decide to keep it for themselves).
... Whether or not they did do this in the past, we should discuss that with Sasuke. This is sensible policy going on that can make the Uchiha immediately useful as soon as one has the time (and elemental nature(s)?) for this, and being used as a teacher for whatever technique people want others to learn also entails being exposed to many techniques of the village, making the teacher, and the Uchiha with whom they'll share it, *also* immediately more powerful. It's not just win-win, it's win-WIN.
If they didn't do that already, saying that makes us useful, and then Sasuke owes us for making his clan even more of a needs-to-be-used, and Leaf also owes us for the boost, and for making the Uchiha more loyal (since their social standing rises as the people of Leaf give them both money and power, as long as they do the work).
