I meant ND-related MAC-layer broadcasts. L3 multicast turned in L2 broadcast.
But I see that the paragraph needs clarification, will do it for the next publication.

I do not have a crystal ball for that. Look at Ethernet, now in the 100s of Gigs in the DC.
With the overlays and distributed cloud, the desire to eliminate broadcasts is more intense than ever.

Keep safe,
