I've never seen another repo with public commit access like that. I guess the project is niche enough that you don't get spammed with bad or malicious commits.
When pugs (a perl6 implementation in Haskell) was a thing, you gained commit access by asking and it was immediately granted to everyone. It was insane and awesome.
Yeah it's basically anarchy (to some extent)

>The idea is to provide unmoderated side channel for random contributors to work on a project, with similar rationale as e.g. Wikipedia - that given enough interested people, the quality will grow rapidly and occassional "vandalism" will get fixed quickly. Of course this may not work nearly as well for software, but here we are, to give it a try.
