All handshake packets are always padded to the maximum packet size to ensure the path supports the chosen MTU.  So if the path doens't, the handshake fails.  This has proven to be a very practical approach, only removing <1% of users who don't support 1350/1370 MTU sizes.

Conveniently, the CHLO needs to be padded for anti-amplifications reasons as well.
