I like the idea of explaining it as "push.default=simple uses the
configured upstream branch, with the restriction that the upstream
branch must have the same name".
But as I learned from you earlier in this thread: https://lore.kernel.org/git/pull.1964.v2.git.1757703309.gitgitgadget@gmail.com/T/#m896f4a32ca462d69637b56f9bdfaa61e55e6b952
push.default=simple will sometimes push the current branch
to the remote branch with the same name even if there's no configured
upstream branch.
So it seems more accurate to say that push.default.simple will push
to the branch with the same name, with the restriction that you might
have to set an upstream, because the branch must always have the
same name, but whether or not you have to set an upstream depends
on the situation.
Personally that behaviour seems unintuitive to me: I always
thought that push.default=simple _did_ require you to set an
upstream branch and after spending many hours thinking about I still
can't really describe in a way that feels satisfactory to me why
it sometimes doesn't and under what conditions that happens.
One idea I had was to change Git's behaviour so that push.default=simple
_does_ require you to set an upstream branch, and then we could
document that behaviour. That's how it used to work when
push.default=simple was originally created and it's not clear to me if the
change to make push.default=simple _not_ always require you to
set an upstream was intentional or not. I did a git bisect to find out when
this changed, and it was in https://github.com/git/git/commit/ed2b18292bfeedc98c9e2b6bd8a35d8001dab2fc
commit ed2b18292bfeed
I tried to write a patch to require setting an upstream branch, though my
commit message has some mistakes and I'm not at all sure of my
understanding of the code.
