I don't really get it. I have never had any problem to see "what is
actually here" in a Python source directory, despite the presence of pyc
files.

Well, I was assuming that everyone had been using svn:ignore,
or .hgignore, for years.
Similarly, you will configure svn, hg, or any other system, to ignore
__pycache__ directories (or .pyc files) so that they don't appear in
"svn status".

It's still mostly cosmetic and I don't think it's as serious as any
positive or negative system administration effects the change may have.
