Maybe I am missing the obvious but how the « pipe to “guix repl” »
approach could be an interactive REPL?

Yes, as any issue before being reported. ;-)

I do not understand your point.  You are mixing 2 topics:

 - Emacs front-end for Guix
 - Scheme mode for Emacs

and then applying kind of transitivity: Geiser is poor (compared to
SLIME or SLY) so it cannot be used for Guix at all.  Applying the same
trick: the number of packages in Guix is poor (compared to Debian or
Nix) so Guix cannot be used at all.

If your point is: shared code from « pipe to “guix repl” » could be used
both for an Emacs front-end and a Nyxt one, then maybe… And even I am
not convinced.

Right, I misread. :-)

You do not convince me.  Because you do not answer to the question: how
one could work interactively without Geiser?  How «pipe to “guix repl”»
could lead to interactive work?  For example, persistence between 2
calls.  And solving that is somehow inheriting from ’comint-mode’ and so
more less rewrite ’geiser-repl.el’; but Guix specific only.  Maybe I am
missing the obvious.

Maybe «pipe to “guix repl”» could simplify what “guix-popup” does.
Even, I am not convinced.

Today, the real issue with Emacs-Guix is not Geiser, at all.  The usage
is often annoying because Emacs-Guix is in low-maintenance mode.


Well, at the end, the only judge is the effective code. ;-)
