I just subscribed to guix-devel and happen to see this email.

I had similar thoughts before, that is putting all profiles under single 
directory.

I was conceptualizing this:

The way we track or mark a particular generations as current generations, I 
think we can apply same concept to profiles. For example, instead of having 
'default-profile' in one directory and others in 'extra-profile' directories; 
all profiles will be put under one directory. There will be first initial 
profile '0' created automatically for each user; just like how system 
generation '0' is created. Then, a user can create as many profiles as they 
want. It will be tracked as 1, 2, 3 and so on. But here we can a tag something 
like 'default'. similar to 'current' tag for generations. User can change which 
profile to be default through `--change-default'; just like 
'--switch-generation'.
