I tried this and it works, but what's the big deal?
It provides a PKG-INFO file that has identical content to the old egg-info file,
an empty dependency links file, and a top_level.txt file with the one line in

Why is this better (I'm not a huge upstream developer of Python stuff, but I do
do some and I don't see what this gets me)?
