I do not recall the exact history, but I would not be surprised if git
first learned to push to a URL, and later learned about configured
remotes.  I do not use it that often myself these days, but I find it
occasionally useful for one-off pushes (e.g., pushing a normally private
repo to a temporary publishing point to share with somebody else).

In that case, upstream branches are not touched at all (because we do
not have a configured remote whose fetch refspec we can examine).
