I think I was the one who prevents the consensus.  To make it clear, I'm
for the suggested solution, but only *after* giving a user a freedom to
avoid loading such a heavy command as "guix package --search-paths".  On
a "usual" GNU/Linux distro a user can edit /etc/profile, but on GuixSD
it is not possible currently.  That's why I think there should be
provided a possibility to override /etc/profile at first.

This is what I do to combine my profiles (I don't use ~/.guix-profile
but several other profiles instead).
