“pre-inst-env” really should not be used by people other than
developers.  It is only available when building Guix from a clone of the
git repository.

We do not recommend “pre-inst-env” for any other purpose than to make
changes to the code, so I would not like to document the quirks and
limitations of “pre-inst-env” in the manual, as this is not how Guix is
supposed to be used generally.

I’m wary of adding this for similar reasons that Ludo wrote earlier.  In
my opinion this ends up cluttering the manual with notes and what I
consider to be only tangentially relevant for readers of the manual.
