Happy Eyeballs doesn't solve things working badly (=ratelimiting),
unfortunately, neither does it help in detecting PMTU blackholing.
What's the bucket for ratelimiting? (Given that it's also a memory
question how many buckets can be opened for this.) Because if enough
people use QUIC, ratelimiting should be across all users and hence HE
should work? Of course it would not if ratelimiting is per (srcip,
dstip) tuple or something in which case it would only fail after the
initial ramping up phase.
At least there is TCP PMTU blackhole detection in modern TCP, I
couldn't find any reference to this for QUIC in my 10 second google
search.
What Lorenzo said.
