It is hurting because there is no clear explanation of the process.

I see an issue with "automatic" decision after a period of time.
It puts a lot of pressure on the community to check everything.
I agree we should state this kind of default. But we should add two
exceptions:
	- new API or API change
	- a maintainer explicitly ask for a techboard discussion

I think the first thing to improve is the decision process.
Increasing the number of committers, without agreeing on a clear
decision process, would make things worse.
