Per upstream announcement [1], I think the API change is related to extensions
only, so the only affected package (in Fedora Rawhide) is IMO gawk-xml.
There's btw. something like (so new package):
Requires: gawk(abi) >= %{gawk_api_version}
Requires: gawk(abi) < %(echo %{gawk_api_version} | gawk -F. '{printf "%d.0\n", $1+1}')
I would encourage you to standardize the way how the gawk(abi) is obtained from
existing installation so the extension providers don't have to do such ugly
hacks... and also, I doubt rebuild of any other package is needed.
