Nixpkgs committer proposal: Mentor assignments

[infinisil]

This is just a thought for @Mic92 @jtojnar @NickCao's delegation of Nixpkgs commit access:

It would be really good to assign a mentor to every new committer, who they can ask for any help with committing, or escalate issues to they don't feel qualified to handle.

Here's a concrete idea:

• Create an issue pinging all Nixpkgs committers, asking them whether they'd like to be a mentor or would like to get mentored on commit access.
• Assuming there's enough mentors, assign at most a couple mentees to a single mentor.
• Assign every new committer to a mentor the same way.
• Figure out some process for graduating from a mentee to a mentor, perhaps at the recommendation of the mentor.

How does that sound?

It could be a bit difficult to find good mentors that also would work well with the new committee. So I am wondering, if the person that proposes someone, should be either the mentor or for self-nomination they maybe should find a person themselves.
