Last time I checked `dpkg-buildpackage -b` was mandatory to be supported
the very same way of -B (and -A is RC only since very few weeks).

Be aware that ubuntu's autobuilders use -b for the architecture where
they build the arch:all (currently amd64, was i386), for example, as
they implemented arch:all autobuilders long ago when -A was not
supported.
I agree that this is Debian and we're testing Debian, but really -b is
not going anywhere :)

Indeed.
I'm fully open to such tests, but imho they would need to be on a
different project.
Besides, atm we don't really have spare resources around…

That's an overstatement: packages most usually build just fine ^^
If the they fail to build is a altoghether differnt problem than just
reproducible build indeed, and we're not so much concerned (as they
don't block our general work really).
