Neat!

Maybe ‘program-wrapper’ or ‘program-wrapping-procedure’ or
‘program-wrapping-phase’ to suggest that it returns a procedure?  (I’m
not sure “language” is helpful.)

Nitpick: the GCS now recommend straight quotes in ASCII, like 'this'.
:-)

Otherwise this and the 2 subsequent patches LGTM.

Could you make sure that the resulting wrapper is the same, either by
rebuilding one way or another as discussed earlier, or by running the
code “by hand” on an example, maybe in ‘guix environment’?

After that you could commit in ‘core-updates’.

Thank you!
