Kernel module serial_ir missing in Fedora 31, 32 (possibly 33)

The serial_ir kernel module for homebrew IR receivers is missing since a number of kernel releases in Fedora 31 and 32, possibly also 33, if I look at Tree - rpms/kernel - src.fedoraproject.org

Who can help to resolve this issue? bugzilla.redhat.com has been unresponsive from my perspective (reporter, commenter), and appears to be the wrong channel for Fedora users?
