Yeah, learned about it while reading the documentation of Fossil (from the same SQLite people). Their approach certainly has its own merits (and drawbacks).
Just wondering how they will transition once the original few people at the top of the hierarchy need to retire, eventually it will happen.
I guess they need to find younger trusted committers with the same dedication and spirit. That's not necessarily easy. But for a piece of software as important as SQLite, I have a feeling they will find those.
The problem with “future worry”s is that the Universe doesn't always agree with us on when that future will be, and it often happens to be closer than expected, even more often closer than desired.
