I don't want to elaborate the specifics in something that gets archived.
If you want to know what precise checks are performed, read the source
code.

In principle, yes, you are wrong: PyPI may accept uploads even if the
metadata are malformed.

Ah. In PyPI, there are two kinds of "write" interactions:
"registration", and "upload". The latter is what brings distribution
files on PyPI. This is the one I'm talking about.

The registration is *only* about metadata (i.e. no files at all),
and it does check the consistency of the metadata.
