Thanks!  This motivates me to resume what had been discussed here [1]:
be able to somehow run:

--8<---------------cut here---------------start------------->8---
 guix build emacs-magit emacs-foo emacs-bar --with-input=emacs=gccemacs
--8<---------------cut here---------------end--------------->8---

At least, have a package transformation that allow to rebuild all the
Emacs packages with the ’gccemacs’ VM instead of the current Emacs 27 one.

What do you mean by “parameterization machinery”?  The new
’with-parameter’ introduced here [2] or the package transformation that
replaces all the dependencies (explicit and implicit).
