Sorry, "nothing" was what I meant. Those non-simple branches are
left unconfigured with ASU=simple. We both agree that the user does
not want to see the "with push.default=simple you have, you cannot
push from it" but the reason why they do not want to see can be
multiple. You are assuming that they want to push to somewhere
else. I am taking into account that they may not want to push them
at all, but only use locally. If the intended workflow is
git checkout -b main [origin/main] ;# assuming DWIM is on
git checkout -b topic origin/main
... work work work ...
git checkout main
git merge topic
... test test test ...
... ahh, no it does not work, back to fix topic ...
git reset --hard ORIG_HEAD
git checkout topic
... work work work ...
git rebase -i ...
git checkout main
git merge topic
... test test test ...
... yay, this time it is perfect and we can push it out ...
git push
i.e. matching "simple" branches like main are used to locally bundle
what you locally worked on, and the result is pushed out to the
other side from there, while non-simple branches like topic are used
to locally work on your real changes, it is reasonable to expect
that the user wants "git push" to fail when the 'topic' branch is
checked out.
But unfortunately that does not work at the last step, as "nothing"
unfortunately affects the last step that tries to check out 'main',
too. push.default='simple' would make it work.

Yes, that is very well known, and there arey mechanisms to support
some workflows that separates "where I get changes from" and "where
I publish my work" (look for "triangular workflows" in the list
archive).
The thing is, "simple" is *NOT* meant for triangular workflow. It
was to cater to novice users who are used to cvs/svn style
centralized "there is one place everybody pulls from and pushes to,
which is where they meet" model.

Yeah, I meant to add the matching (when ... is set to ...) after the
sentence and forgot. You inferred what I meant to say correctly.

FWIW, I am not.
I do not think it is healthy nor necessary to make your local work
"catch up" too often with the outside world unnecessarily, be it
done with rebase or with merge. They _can_ update 'master' when
outside world has something worth adding to your topic extra
dependency on and then update 'topic' to include what you took to
'master' from the outside. Dissociating the 'topic' from outside
world is one way to encourage a better workflow.
