Please tell us about the lost potential of Kumogakure; it sounds like it'd be a very interesting discussion!
Thank you for asking! I apologize for this taking LITERALLY eons but.... finals. Actually died for a few weeks there.
I think it's such a missed opportunity that so few of the other villages' systems ever get explored. Kiri is another good example (I wish we got to see more of Mei repairing that shit). We're told how these issues tie into various characters' motivations (for Kiri, Kisame, etc.) but we never really get to see how they were. The issues in practice. Etc.
We're told about how each of the villages have their own systems for how they function, and personally I think Kumo has such an interesting one.
The "A" and "B" system are so fascinating. Having the A choose the B, having B become a Jinchūriki a bit later, letting the next B learn from the former... it all makes so much sense. It really seems like it would lean to a much more stable sense of self for B and a more stable relationship between the Kage and the Jinchūriki.
In practice, we see that it helps A4 and Killer Bee a lot. Where so many other Jinchūriki have been so ostracized, comparatively Bee has so much more protection from A4 and it allows him to be a lot safer. (Not that it's perfect. Obviously there's still major conflict between Bee and the village, but it's absolutely mitigated as opposed to others.)
Honestly, though, I think Kishimoto kinda shot himself in the foot with the creation of Kumo. He's created a village with a more or less unarguably better system for the Jinchūriki, a Kage who's successfully led for a fair amount of time, and one that's led to none of its members joining the Akatsuki. Basically, it's clear... something is going better. And that's never really addressed.
As with anything, it's ultimately an issue of Kishimoto not properly tackling the topics he introduces and dropping interesting plotpoints constantly.
I know a lot of people really dislike the war arc (and very fairly), but the summit arc is extremely interesting to me because it had a lot of potential. I think it could be extremely fascinating to see the different systems the villages have implemented and how that could lead to conflict or improvement or what have you. But instead we just get... war arc
