I think pypi.debian.net does not mangle the file names in any way, it just
takes them from upstream PyPI verbatim.

And the change from - to _ is caused by more build tools adopting this
specification [1], which says:

“In distribution names, any run of -_. characters (HYPHEN-MINUS, LOW LINE and
FULL STOP) should be replaced with _ (LOW LINE), and uppercase characters
should be replaced with corresponding lowercase ones.”

This link is for binary distributions, but there is a separate specification
for source distributions [2] which says that rules are the same.
