I want "-q" rather than "-Q" because I want the Emacs instance to
autoload the Emacs packages that I've given as arguments to "guix
environment".

Maybe I'm underestimating all the ways people use "guix environment".
When I use it, I'm interested in getting an isolated environment,
usually for testing, and in this case I don't want the Emacs packages
from my profile.

But sure, I can use "emacs -Q" and then evaluate something similar to
what Guix puts in site-start.el, modifying it to only look at
GUIX_ENVIRONMENT.

I certainly agree with that load-path should include emacs-wget.  I'm
just not sure I agree with the "along with".

Anyway, as I said above, it's easy enough to get the behavior I want
with "emacs -Q" and a custom guix-emacs-autoload-packages call.

Thanks for your thoughts.
