Comment:
For what it's worth, we also use a bunch of `GNOME_SITE`, `PYPI_SITE`, etc, across distfiles. In my opinion, those are kinda worse, since the link can't even be found in the template itself, and I have to open another file to find it. If we decide to make `${homepage}` "forbidden", we should remove those variables as well.
