Happy eyeballs doesn't solve PMTU blackhole.

So this is actually customer breakage occuring, but I imagine lots of ISPs 
are actually doing MSS re-write and/or announcing lower than 1500 MTU on 
the customer LAN, so even if a customer has PPPoE with 1492 MTU, they 
still won't see this problem.

I have seen swedish authorities websites with same "won't-respond-to-PTB", 
no answer there either to fault reports.
