The PR spec for some open source projects are quite onerous.

What is unspoken here is that some open projects are using cost of submission AND cost of change / contrib as a kind of means of keeping review work down.

Nobody is correct here really. It's just that the bottlenecks have changed and we need to rethink everything.

Changing something small on a very large project is a good test. A user might simply want a new optional argument or something. Now they can do it and PR. But the process is geared towards people who know the project better even if the contributor can run all the tests it is still not trivial to fill in the PR request for a trivial change.

We need to rethink this regime shift a bit.
