RE: filtering /48 is going to be necessary

I haven't heard anyone advocate accepting less than a /48. I think /48 is a reasonable "You must be this tall to ride" barrier.

Beyond that, YMMV.

Apparently AS6939 has at various times :) I remember getting some /64 announcements from HE. I haven't seen one lately, though. I'm only filtering one /64 route these days announced by AS4651
