bug#36335: Is /dev/kvm missing ACLs?

Hi,

I was trying to run some VMs via "guix system vm", and I noticed that
I didn't have permission to use KVM.  This issue can be worked around by
running qemu as root, or by adding yourself to the "kvm" group.
However, I found it curious that the /dev/kvm device didn't have ACLs
granting me access:

--8<---------------cut here---------------start------------->8---
$ getfacl /dev/kvm
getfacl: Removing leading '/' from absolute path names
# file: dev/kvm
# owner: root
# group: kvm
user::rw-
group::rw-
other::---
--8<---------------cut here---------------end--------------->8---

Is it expected that on Guix System, /dev/kvm does not by default receive
ACLs granting me access?  I'm logged into a GNOME session via GDM, and I
was under the impression that logind or udevd would automatically set up
ACLs for me to access local devices, such as /dev/kvm and /dev/sr0, in
this case.

Note that I DO have ACLs for some other devices, such as video0:

--8<---------------cut here---------------start------------->8---
$ getfacl /dev/video0
getfacl: Removing leading '/' from absolute path names
# file: dev/video0
# owner: root
# group: video
user::rw-
user:marusich:rw-
group::rw-
mask::rw-
other::---
--8<---------------cut here---------------end--------------->8---
