Yes, that's annoying. I think it has to do with grafts; when a package
must be grafted, all its output must be available. Grafts complicates
many things, but unfortunately they are necessary to provide timely
security updates.
I don't see a bug anymore for that one, we should try to improve things
here; feel free to report it to bug-guix@gnu.org, perhaps with a title
like "grafts cause all outputs to be downloaded". Perhaps a solution
would be making graft derivations substitutable (currently they happen
on the local machine).

Could you write it? It's clear you know much more about what's going on
under the hood.

If this is what I suspect it is, the only way would be ‘guix shell
--no-grafts’. This will disable any security fixes that haven't
yet made it to master.
I don't recommend it, beyond testing it to see if grafts are
indeed to blame, and perhaps narrowing down how.
> Is this a bug?
If it is due to grafting, it's a long-time known annoyance, yes.
I searched (twice) to find a specific open bug report to give you,
but found nothing.
(Almost certainly a failure on my part; don't open a new one ;-)
I say annoyance because it's nothing more for most people, but if
bandwidth is a serious issue for you the best way to see it fixed
is to dig in.

All generalisations are false, as they say:
~ λ guix shell qtbase
…
19.4 MB will be downloaded
qtbase-6.3.1 18.5MiB …
𝕘 qtbase ~ λ exit
~ λ guix shell qtbase:debug
…
321.6 MB will be downloaded
qtbase-6.3.1-debug 288.2MiB …
𝕘 qtbase:debug ~ λ exit
Kind regards,

I assume it's related to grafts:
(ins)efraim@3900XT ~$ guix shell qtbase@6
321.1 MB will be downloaded
qtbase-6.3.1-debug 287.7MiB 3.7MiB/s 00:01 [ ] 1.4%^C
(ins)efraim@3900XT ~$ guix shell --no-grafts qtbase@6
(ins)efraim@3900XT ~ [env]$
exit
Looks like it downloads all the outputs so it can perform grafts on all
the outputs, and only then does it put just qtbase in the environment.

Yes, and this is because grafts have been marked as non-substitutable by
choice, for performance considerations. Would revisiting this choice
helps here (making graft derivations substitutable?).
