IMHO, we should have a generic alias system "à la" Git or an UI
modifier via channel.

It is not reasonable to duplicate all the commands just for
convenience. Because convenience mainly depends on personal
preference.

The same way that we add "guix workflow" or "guix home", a forward
move should to package some "guix flavor", e.g., add the command "guix
profile" via channel (or package). Then simply "guix install
guix-profile" will add the very command.
Konrad already proposed similar.

I agree. David proposed that in "The future of 'guix environment'".

https://lists.gnu.org/archive/html/guix-devel/2017-08/msg00300.html

And as Konrad mentioned, I prefer "--inputs-of" instead of "--devel".

Let bump the version and break compatibility. :-p

And to be consistent, why not add a similar option to manifest (via
"package-environment-inputs" exporting as "<option-name>" same than
"--option-name"; I opt for option-name equal inputs-of instead of
devel :-))
