And there was a perhaps small, but certainly non-trivial stream of
people asking how to change that because their system(s) were indeed
multiple ports connected to the same broadcast domain.

Long since then Sun changed their defaults, and we've gotten things like
bonding, so I think any assumption that a system with multiple ports
will not have then connected to the same broadcast domain is brittle at
best.
