I think it is. @{publish} is like @{upstream}. Period.

And I disagree.

Yes, but we are not talking about 'git push', we are talking about
@{publish}.

I think of @{publish} as "the branch the user has configured to push
to"; it overrides all other configurations (push.default and push
refspecs). I wouldn't mind having a @{push} *in addition* to @{publish}
that would have the behavior you mention, but for @{publish} I'm pretty
certain the behavior I want is that it maps *directly* to what the user
has configured.

Similarly, I don't want 'git branch -vv' to show @{push}; it would be a
mess to show something on all the branches, probably origin/$branch, and
probably all "ahead/behind". I want it to show @{publish}, so only the
branches the user has *explicitly* configured.

It doesn't mean that to me.

For the record, I've been thinking about this for a long long time, and
I argued for @{push} and @{publish} long before you discussed this in
January (which apparently you forgot). I implemented this more than half
a year ago, and have been using it since; it works great. The problem of
triangular workflows is pretty much solved for me.
