Yes, definitely!

It’s mostly that ‘guix weather --display-missing’ is not really helpful
when passed more than one URL: it reports all the things that are
missing on at least one of the URLs (this is what the comment in
‘Makefile.am’ suggests).

The goal of this command is to check that “basic packages” build and are
available, and we can expect basic packages to be available on both
build farms so I think it’s OK to check just one of them.  (When I first
wrote that manifest, I naively thought we’d be at 100% at any time since
this is really the baseline…)

For i586-gnu the expectation is really low right now: see
‘%base-packages/hurd’ in ‘etc/release-manifest.scm’.
