Ouch.  “It used to be” (speaking like a veteran :-)) that Emacs in Guix
would not use EMACSLOADPATH.  Then we switched to EMACSLOADPATH, which
had some advantages, but necessarily has this drawback.

IIUC, <https://issues.guix.gnu.org/45359> is about possibly
backtracking.  Maxim, what’s the status of this one?

Thanks,
Ludo’.
