Back in 2008 most people hadn't had their networks fall over as a
result of MLD listener report implosions when a thousand machines
report (via multicast, natch) their eight[1] single-member

Some of us have seen what happens when one machine reports eight
hundred single-member solicited-node multicast groups in the space of
a few milliseconds.
