Champion Ships and the Navy
Or how the core idea of the Tarkin Doctrine can be more reasonably applied.
The ISD, while a remarkable ship with few peers, isn't suited to fufill both it's role as a main workhorse ship and as a true symbol of Imperial might. Because as ideal as it may seem currently, perceptions, much like reality, have a tendency to change. And producing the ISDs required to make it the workhorse of the navy is exactly that.
Now why would that be? After all, an ISD is still an ISD no matter how many are made right? But well, not really. Not only would having so many ISDs increase the chance of an ISD falling, ranging from crew folly, a cunning trap, or poor maintenance rearing its head at a bad time. It would also risk normalizing that type of craft, losing some of the intimidation factor through exposure. Simply put, the rarity of such a ship also serves to highlight the feeling of it being special, powerful. Something which is hard to preserve when it starts appearing everywhere, which both would weaken the psychological impact of it's presence, while also serving to create a level of predictability, as no design is perfect and our enemies will learn the flaws of the ISD, whether we are aware of them or not.
There is no such thing as a perfect design, the realities of design and research don't allow for it. So ideally, we should instead of seeking multirole perfection in big ships, reconsider our approach and instead design a Star Destroyer that would, instead of functioning as an everything ship, focus on being something to be deployed when serious escalation is required. Not only would this preserve a degree of gravitas to the design the ISD may lose in fulfilling it's intended role, as it may instead lead to ISD scale turning into the new normal, sapping some of the intimidation of the design as it's prodigious size loses the significance by becoming normalized.
I fully recognize that the ISD if used as currently planned would still make the ISD and it's design into a symbol of the empire. But, perception is something that can change drastically from different context. As envisioned, it is likely it would go from being a symbol of power to merely a symbol of the empire, as people get used to seeing such ships often. Especially as raw statistics dictate that every new ship added to do standard duty, the more chances the stars may align an incident that weakens the perception of power. Whether it is the ISD failing to capture a fleeing quarry, a ship seized in a boarding or mutiny, or force forbid, destroyed in a battle it shouldn't have wound up in in the first place. There are quite a few ways that one could damage the perception of absolute power here that we want to foster. While my proposed method is in no way immune to those potential problems, especially with the fact they are supposed to be fielded to deal with more troublesome problems. The policy would both lessen the numbers that must be kept in full operation, while also possibly helping mitigate loss of face should threats prove tougher than expected, due to their deployment in the first place being a sign that the Empire recognizes the trouble as a threat. Or it might not, psychology is complicated, and either way, having champion ships that serve as a symbol of strength should help manage the difficult task in allowing them to fill their role.

certain video. While it is only about perceived value of a purely digital item, well...
Since it's psychology, it probably does also apply here to a degree, as well. The Empire did undermine the psychological weight of the ISD by producing and using so much, it became less of a symbol of might, and more of both a symbol o the empire and a standard ship, which may have factored into projects such as the Executor, to create something head and shoulders above the workhorse ISD. And well, this is probably a radical take on big ships doctrine. Big ships good, but emphasizing the intent of the big ships being big deals, and wanting to focus on that by taking a path to try and either delay or preempt the escalation that leads to the Legends Star destroyer situation. Essentially aiming at less multirole everywhere craft, but a few craft that would instead deal with crises, being special troubleshooter ships instead of the envisioned one for every planet.
