I do not think there is no "want to declare" involved. If I
correctly recall how "push -u" came about, it was merely a way to
appease those who complained that their new branch created by
running "checkout -b branch origin/branch" has already set up the
branch.*.remote and branch.*.merge configurations nicely for them
and allow them to immediately go ahead and start using the
centralized "I merge from their 'branch' and push to that", but when
they create a new branch on their own and want to make the branch of
the same name at the origin to be the "upstream", they have to futz
with the configuration. The declaration was made long time ago when
we started using @{upstream}, and there is no new extra confusion.

Correct; I am not saying "where do I publish" is never relevant. It
is just it is not something useful for "format-patch" to use as the
default fork-point.

Yes. But most likely, if you always push a single branch to
multiple places, it won't be like you push it to only one of the
places today and another one tomorrow, leaving everybody out of
sync. Unless there is a site that is temporarily down, in which
case that one may stay behind, the normal state would be that all of
them point at the same commit (that is how I publish to multiple
places anyway).

Yeah, I think in the 2.0 world with pushdefault (i.e. triangular),
the default 'simple' turns into 'current'.
