With Git you can work in, well, at least twelve different ways. But people discuss workflows with some built-in assumption that of course everyone else is using it like they are.
FWIW for individual repos I don't even use PRs so the whole issue of how to merge them is moot.
The point? You’re not making sense.
This is a discussion. This is not your team pow-wow where the boss makes a show of hearing everyone out and then going with what he decided with beforehand. Or whatever your process is.
This right here is a discussion. It makes no sense to pull the “we all wear leotards because that’s the team policy”. That’s not an argument that I can recognize.
You should, in a discussion, make where you come from clear. If three comments in on the topic of X you say “but of course we use Y, how dare you suggest something else than Y?” then you’re not having an argument any more.
We constantly use that on the OSS project I’m occasionally involved with. “Well why is it like that…” and the project has enforced a good history so this can often be answered.
And that’s the primary benefit of Git. With some discipline the history becomes legible.
On the other hand it doesn’t give you much out of the box for code review. Unless the code review you use is covered by the email tooling.
