I'm very interested in the second part as well but unfortunately it's
not something supported by Guix without resorting to hacks, as you found
out. I never had the time and/or energy to dig deep into it. You went a
lot farther than I did!

This is a pity, because it doesn't look like this use-case would be hard
to support in Guix and I think it would be a killer feature for
developers, allowing it to gain more popularity as a development tool.

I don't know the answer to these questions, but your solution is
ingenious!
