it still exists on older distro and the package is built for those.

Your jokes were already better.
This package does not build for older distros which still support SuSEfirewall2, and will stop building in the near future for distros not supporting SuSEfirewall2 anymore (which includes SLE15). Which means we can drop it as it would not build anymore anywhere?

4 months for a simple build fix sounds like long enough. The veto was countered, without further reaction.

The package already now only builds for Leap 15.0 and newer (base don firewalld)
