Hello,
$SUBJ is coming to F38 (and later F37 and 36- well tested).
Here's the bodhi update:
https://bodhi.fedoraproject.org/updates/FEDORA-2022-cba07364fb (will be
merged momentarily).
Here's the test log:

Let me know if you have any questions or issues (I have not tested rebuilds
of other packages yet).
Regards,
Pavel
