Sounds very useful to me!

Sounds good. I think I prefer ‘emacs-’ to ‘el-’ because that’s probably
what people expect.

guix.el already takes care of that (info "(guix) Emacs Initial Setup"),
so that should be enough.

Rather %install-suffix (“path” is used exclusively to refer to search
paths in GNU.)

Please align the lets. :-)

Should probably use ‘emacs-batch-eval’ from (guix build emacs-utils),
and perhaps define ‘emacs-byte-compile’ there.

Yes, should probably be moved to (guix build utils) eventually.
Thanks for the great initiative!
