Ah, ok, so it's more of a tool to work out who can have responsibility
to direct access to a particular repo and be trusted not to muck it up.
I guess it also reduces the workload for a maintainer accepting/merging patches, which is a good thing!
But, wouldn't a trusted developer be known to the community anyway, namely the time/effort/dedication to a project would already be known to his/her peers?
Seriously, I am not trying to criticise a particular distributions policies for commit/upload access to their repos, but talk of "quizzes" has the very faint smell of Corporate HR filtering tactics, and in some ways perhaps a little bit patronizing, wouldn't the fact that google exists and the answers are easily discoverable mean you would have to fall back on a particular developers community reputation anyway?
