For example, naev used to work just fine, yet apparently it doesn't 
anymore: https://issues.guix.gnu.org/65390.

Given that Guix has ci.guix.gnu.org, I would expect such new problems to 
be detected and resolved early, and it was detected by ci.guix.gnu.org, 
yet going by issues.guix.gnu.org it was never even investigated.

(Yes, there is a delay, but that doesn't matter at all, as there's this 
dashboard <https://ci.guix.gnu.org/eval/668365/dashboard>.)

Do people really need to report 33% of all jobs 
(https://ci.guix.gnu.org/eval/668365/dashboard) before those failures 
are taken seriously, instead of the ‘there don't seem to be that much 
more build failures from the core-updates/... merge, let's solve them 
later (i.e., never)’ that seems to be  status quo?
