Thank you for the PR Martin. 

Just for my understanding: the requirement to pad client initials from the second flight onward (i.e., after receiving server packets, ACKing server initials) is purely for convenience. It is not necessary for PMTU or anti-amplification-allowance. As such, the limit should also not be enforced at intermediaries wholesale?
