I disagree. As it is, tools like Twine only introspect the more common
file formats to upload them to PyPI and has not had a single user
complain about it. Given that Twine is advertised as the preferred
method to upload to PyPI, you might expect that this would have been
requested already. Alas it has not. No one using modern tooling for
package management is uploading these file types.

Even if the statistic of downloads (which actually is valid) doesn't
sway you, maybe this will. Alternatively, maybe you will help maintain
support for these file types in Warehouse?
