For completeness, I'll share too ;)

The domUs vifs naming scheme change has been mentionned in the Bookworm 
release notes.
I suggest everyone reading them BEFORE upgrading, as it can prevent a 
lot of surprises !
https://www.debian.org/releases/stable/i386/release-notes/ch-information.en.html#xen-network

There is also a Debian bug about it (although created after your mail 
here) :
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1042842

It may contain useful information concerning your firewall domU.
