Debating things is a one-time cost, whereas potential time savings/time
increases will be a gain for all future users / a loss for all future
users. Also, didn't you ask for comments on your proposal, implicitely
by sending to guix-devel@ and explicitly by

Seems like a false dichotomy, why not: Alice teaches Guix to do the
equivalent of rolling a six-sided dice, so she doesn't have to figure
out a bundling and she doesn't have to manually roll dices. Now,
teaching this is a bit of a time investment, but she shares it with all
other Guix users, so everyone benefits of automatically better
performance.

I assume N-sided die = N-separate profiles here? If so, not sure what
the 'fair' is about? Taken to the extreme, why not N separate
profiles, where N is the number of packages?

I don't? Well, initially I didn't see a reason for multiple profiles,
so I asked for reasons, and eventually, a few reasons that weren't
addressed yet by other things were mentioned (e.g.: tidyness of
separate profiles, some kind of minimalism where one only has packages
in $PATH and other search paths that are currently neccessary by
manually activating a profile that has a selection of packages)?

(2) is already achieved by "-p".
(4) is already achieved by "-m/ no -m"
(3) not sure why the user would care about /var/guix/profiles/per-user
(7) is already achieved by "guix install" / "guix package -m". The
‘source on login’ isn't though -- half-achieved?
Remains: (1), (5), (6), (7) not yet completely achieved.
This kind of list was what I was asking for.

The extra Guix Home feature magnifies the problem of search paths, so
it seems a point of discussion here to me. Especially since solving it
for Guix Home profiles seems a lot less complicated than the general
case to me: just compute the set of search paths (combined over all
packages in all the profiles) and use these search paths for all the
profiles.
Greetings,
Maxime.
