That seems ridiculous.  Has anyone tried getting in touch with them to
get their arguments about why inventing another variable that means the
same thing was necessary?

I'd much prefer challenging that stance than "endorsing" it in Guix :-).
I think it'd be OK to reluctantly add it in as a stop-gap fix in Guix,
but *only* after opening an issue to discuss it upstream and linking to
that issue in Guix.

Thanks,

Maxim
