That's my thinking, as well, but it means the "upstream" push.default is
nonsensical. I've thought that all along, but it seems like other people
find it useful. I guess because they are in a non-triangular,
non-feature-branch setup (I suppose you could think of a central-repo
feature-branch workflow as a special form of triangular setup, where
the remote is bi-directional, but the branch names are triangular).

If we want to declare "push -u" and "push.default=upstream" as tools for
certain simple bi-directional workflows, that makes sense. But I suspect
it may cause extra confusion when people make the jump to using a
triangular workflow.

You _might_ treat it the same way we treat the upstream, in some special
cases. For example, when you say "git status", it is useful to see how
your topic and the upstream have progressed (i.e., do I need to pull
from upstream?). But you may _also_ want to know how your local branch
differs from its pushed counterpart (i.e., do I have unsaved commits
here that I want to push up?).

So having two config options might help with that. Of course, your "push
upstream" (or whatever you want to call it) does not logically have one
value. You may push to several places, and would want to compare to

If that were sufficient, then we would just need "push.default =
current", and not "upstream" (nor "simple"). I lobbied for that during
the discussion, but people seemed to think that "upstream" was
better/more useful. Maybe it was just because remote.pushdefault did not
exist then.
