~/.guix-profile is independent from ~/.guix-home and you don't need to
move all the packages to Guix Home if you don't want it.
The profile management is the same as for Guix System.
~/.guix-home is a synonym to /run/current-system.
Customization of ~/.guix-home location is potentially troublesome and
was removed in October 2021.

A little too abstract/general, let's see how it goes during
