I've just checked files in /usr/share/dbus-1/system.d/ on my Debian host, and there is a lot of files which names correspond to D-Bus service name. What do you think about renaming bluealsa.conf to org.bluealsa.conf?

See "INTEGRATING SYSTEM SERVICES" in: https://dbus.freedesktop.org/doc/dbus-daemon.1.html :

The policy file for com.example.Example1 should normally be named com.example.Example1.conf.

I think that is the "correct" name. The only backwards compatibility issue I can see with changing the name is when an update results in two copies under different names (and also cross-release documentation such as the wiki, but that can be dealt with). So in principle I am in favour of such a change.

I think that in the next release we can go with exec renames (I'll submit PR proposal in few days maybe), so we can do more "destructive" stuff as well :D
