The python dependencies were added to propagated inputs automatically
by "guix import". The other tools are needed in the user profine,
because qmk-cli uses them, for example it fetches qmk firmware from
git, it runs some *python stuff* and when user is done making changes
to their firmware, qmk cli builds the firmware using the compiler and
flashes it using dfu.

I think it would be cool if Guix allowed defining profiles and
environments the same way it allows defining packages.
This way installing qmk-cli would also install say qmk-profile with all
headers (and tools) needed for development. Now, even though
arv-toolchain is installed, I have to run "guix environment qmk-cli" to
be able to work with the firmware without getting build errors.

I need them installed, so qmk-cli doesn't complain. Should the user be
responsible for installing all the tools needed for development?

I'm not sure. That's the first thing qmk-cli sets when it is already
installed. Normally, qmk-cli is installed by pip, maybe it is
responsible for setting the variables?

Should I describe what qmk firmware is or say more about what working
with qmk firmware is, or both?
