We're talking about the people with commit access to the main repo. No
commit access still needs someone with commit access to push/merge.

Practically, if we don't want to change *anything*, non-committers can
have the same process they have today when submitting patches.
GitHub/Lab will just be yet another source repository.

Today, 100s of people commit directly. In a GitHub style, 100s of
people will have to wait for a merge from a few folks. Those few folks
will have the additional job of merging lots of patches. It's more
like GCC, where maintainers are gate-keepers, and not one we have used
so far. I'm ok with it, but other people might not.

My personal preference is to not do that. I can't even cope with
myself pushing to master from different repositories, let alone 100s
of people. But I take it everyone else is indicating that would be the
I haven't mastered git enough to know the pros and cons, but you seem
certain. Can you share your thoughts on the subject?

I think we all know the benefits of using GitHub/Lab, but we already
have Phabricator that does a similar way and kind of cope with it
being on a separate repository. Some people love Phab and Arc, I don't
particularly like it myself and do prefer the GitHub style, but I'm
just one guy.
The main reason to move to GitHub/Lab is one of cost: storage,
bandwidth and uptime, not one of tools. Even if we end up using the
GitHub interface in the future, I think we should consider a less
radical move first.
Of course, if the problems of moving to git but still following our
style becomes prohibitive, I think we should move to GitHub and use
their style, as IMHO, the cost argument is stronger than the tooling.
