Interesting. I too had never heard about this PATH recommendation and it
seems contrary to some advice I do remember given in the cookbook about
working with multiple profiles. For me, activating an extra profile
places it's /bin and /sbin directories at the beginning of my PATH. I can
only find ~/.config/guix/current/bin burried quite deep near the end.

Do you have any advice on how regular end users could follow your
recommendation?

My naive hope would be that end users wouldn't have to think about
it. Ideally if its that dangerous then updating the path would happen
automatically when sourcing the etc/profile file inside a profile
directory.

Should the Guix Profiles in Practice section of the cookbook be updated
to reflect this?
