I agree that a "broken by default" in OpenWRT/LEDE for a variety
of Broadcom devices is not really acceptable.

Technically we could teach netifd in OpenWRT/LEDE to configure
ebtables accordingly, at least for a list of affected devices,
so that users would not have to. However, as ebtables is not
managed by the fw3 in OpenWRT/LEDE, that would probably interfer
with user provided ebtables rules and scripts...

Hm, we could change the default in OpenWRT/LEDE for
multicast-to-unicast (or more precisely bridge hairpinning) to
disabled again for now.
