Are your links or hosts limited in some way or broadcast domains of some unreasonable size? Most of the competent switching or managed wireless products will snoop or otherwise handle this overhead in a sane manner. Otherwise this at best would seem to be an over-optimization.
From my days on a giant campus network the current pps rate of MLD chatter was much lower than the IPX/SAP broadcasts we had from 20-25 yrs earlier.
Hi Dale, Actually, I'm doing station to station encryption with macsec using multiple SCIs at each station so there's a magnification effect of encrypted multicast packets that the switch can't snoop even if it wanted to -- all the intermediate equipment sees is an opaque ethernet frame with the broadcast flag set.
