New packager: Do the reviewer and the sponsor have to be the same

[Michael J Gruber]

I would like to help this poor soul get his package into Fedora:

https://bugzilla.redhat.com/show_bug.cgi?id=860249

(adobe-source-code-pro-fonts)

I'm a packager but no sponsor, he's no packager (so needs a sponsor).
It's not clear to me whether I can just make a formal review and ask a
sponsor to say "yes", or the new packager needs an actual review from a
sponsor (different pages seem to disagree somewhat on this).

An old request for sponsorship on the fonts-SIG list has not been
answered so far, which is why I'm trying to help this way.
