My approach is different (making a templating system around Guix that translates
a number of not yet defined language inputs into a file that can be reused by
Guix), but I think we should make use of the guix system abilities and not rely
on the fact that people could already do this with an external tool.

Do we have the ability to separate features, like --enable-experimental passed
to configure build Guix with certain features that might break your OS? Otoh
we already presume that people setting up GuixSD today know enough about systems
to recover from failures (which is another undocumented problem/usecase with 
GuixSD).
