I think at this point everyone has made their peace with the pip
developers' decision that they want to keep copying files -- at least
for now -- and that's just how it's going to be. This email has a more
detailed discussion of the options, their "threat model", and the
tradeoffs:

I can see an argument for adding language saying that build_sdist
SHOULD avoid modifying the source tree if possible, and MAY write
scratch files to the sdist_directory.
