Canonical maximum sizes can be found at https://fedoraproject.org/wiki/Releases/37/Spins and https://fedoraproject.org/wiki/Releases/37/ReleaseBlocking . This check is run by the 'relval' tool, which has its own list of maximum sizes derived from those pages. If the maximum size used for this comparison is wrong, please add a comment and file a bug against relval at https://pagure.io/fedora-qa/relval/issues and it will be corrected. If you believe the canonical maximum size for an image should be changed, please follow the appropriate process before filing a relval bug.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 37 development cycle. Changing version to 37.
I think this got fixed along the way (or else there'd be more reports).
