Wrong.

People can and do work from more than one private repositories
(I do).  In a sense, that is sharing the repository with
oneself.

I may do an emergency patch to fix breakage on 'maint' (and
'maint' only) from a location that is not my primary development
box and push the fix out.  I fully expect that the push will
push out 'maint' and expect the other branches such as 'master'
on the remote side to stay the same, as I haven't touched
'master' on that box for quite a while and it is now stale.  In
that situation, I _want_ the "git push" itself to report failure
to notify me that it did not push what _I_ asked it to push out,
so that I can be reminded that I'd better do "git push $remote
maint" the next time.  In the meantime, even though it reports
a failure, 'master' on the remote side is _not_ updated, so the
behaviour is still _safe_.

Wrong.  push is a mirror of fetch and does not do _any_
integration.  It is just a safe (because it insists on
fast-forward) propagation mechanism.  Your integration still
happens with pull (actually, shared repository people seem to
prefer "fetch + rebase" over "pull" which is "fetch + merge").

So you do "git push $remote bar:foo".  If you do that regulary,
there are configuration mechanisms to help you reduce your
keyboard wear.  What's the problem?
