I'd prefer allowing uploading of both formats for now, with mild encouragement
to at least include zips.

I'm fairly certain the Debian Python ecosystem in general can consume zip
sdists without problem, although there may be some individual packages that
need some adjustment.  I don't have any sense of large an impact it would be
to switch sdists from tar.gz to zip, but allowing for some overlap with
"gentle nudges" toward the preferred format would allow us to do the analysis
and give us some time to plan a transition.

Personally, I don't much care if the sdist format is tar.gz or zip, and it
does make sense to promote one archive format for both source and binary
distributions.  I mildly prefer tar.gz but for pretty shallow reasons
(i.e. not good enough :): one tool to rule them all (tar(1) both packs and
unpacks, while zip needs two commands), and I've been using tar for way longer
than zip so I'm a little more comfortable with it.

What I'd want most of all is a clearly documented transition plan, i.e. a PEP
that I can point other people to and say "we need to make sure all our tooling
is in place by date X because that's when .tar.gz is going away".

Cheers,
