Clear support for Layus' points.

I'll mention another point more clearly.

Eschew hierarchy & consensus

Adopt the Advice Process:
Before making a decision seek advice from expertise, then seek advice
from those you'll affect. Neither group can veto your decision.
Maintainers who do not do this or are unwilling to do this are loose
cannons and are removed. The bar to becoming a maintainer: 1 PR.
Evidence will amount to see whether the advice process is used or not.

It's a good thing more people feel part of the community. Remove the
loose cannons, the code base then stabilizes greatly.
