If that is what you want to prevent, I do not think checking for a named
remote is sufficient. You can also be pushing to a branch on a named
remote that is not part of your fetch refspec, in which case you do not
have a tracking branch. I.e.:
git clone $URL repo.git
cd repo.git
git push --set-upstream HEAD:refs/foo/whatever
For that matter, I wonder what "--set-upstream" would do if used with
"refs/tags/foo". You would not do that in general, but what about:
git push --set-upstream master:master master:v1.0
I didn't test.

I do not claim to have used it myself. Tightening the "--set-upstream"
behavior would not hurt people who want to configure such a thing
manually, and it might catch errors from people doing it accidentally.
So even though the config it generates is not nonsensical, there is a
reasonable chance it was an error, and tightening may make sense. But I
think you would not want the condition to be "this is a named remote",
but rather "the generated configuration actually has an @{upstream}".
