Is it already possible to choose Btrfs in the graphical installer? I
guess so, but I haven't tried.

My personal experience also tells me so, but it is true that it is still
newer and more exotic than EXT4.

What kind of tests are you referring to? There is a test in (gnu tests
install) that install root on a Btrfs subvolume and boot from it, but
I'm pretty sure the graphical installer doesn't have support for
configuring a Btrfs subvolumes layout.

I'm in favor of encouraging the use of Btrfs with compression given that
Guix puts more stress on storage space compared to traditional distros,
and that I've had only positive experiences with Btrfs in the last year
and half or so that I've used it on my machines.
