Thank you!

My impression is that the Rust packaging in Guix is so problematic that
if a way would mean less work for you and motivate you to push this work
to the finish line it, that may well be the better way :-).

That would match our convention better, if it's not too difficult to
accomplish (is this going to be automated?  I've written some imperfect
but useful automatic rewriting tool in the past to remove the Python 2
packages [0].  Perhaps it could provide some ideas)
