If we update waf again, we currently have to keep the local patch to
python.py (here the reverse, removing it as part of the update):

Do you have any thoughts on a better way to do this?

We also can't import the whole waf tree, or carry it as a submodule, as
that would bring in waf/doc/book which is non-free.  (Carrying that
would cause all distributions, not just Debian, to then have to expunge
it from our tarball, and may even cause issues with our obligations to
our fiscal sponsor, which strictly requires that Samba distributes only
free software).

I know there is a long history here, but can you please consider
re-licensing this, as even having it in the git history makes keeping a
mirror of the waf tree very difficult.
