Would it be valuable to create a `mono` package group in Koschei? I have a feeling that a
few package builds started failing when Mono 5 landed (e.g.,
https://apps.fedoraproject.org/koschei/package/nuget,
https://apps.fedoraproject.org/koschei/package/keepass), but it would be nice to be able
to see that at a glance.
