Ah, I wasn't clear...  I believe it will happen again. 

Unfortunately, it won't be TE more-specifics being
filtered this time, it will be routes covering unique
end-site locations.

>ISPs already filter.  ISPs that continue to use old hardware that maxes out around 240K routes are reportedly filtering somewhat aggressively.  ISPs I've spoken with have said they'll do what they need to when they need to if their routers are about to fall over. I guess I'm just not smart enough to see why ISPs would threaten their own infrastructures just so somebody else's customers can gain connectivity.

They won't...  hence my statement that the end state isn't global collapse,
but it also isn't global connectivity.
