Sending just one copy makes sense if the clients receive carbon copies
anyway; but if they don't, it might go against expectation that delivery
for /A now depends on whether/how /B joined the same room. (Then again,
the routing behavior when multiple clients are used without carbons
probably goes against the expectations of most users anyway.)
