Do we really need to pad all server initial packets to 1200 bytes? As
far as I can tell, RFC 9000 14.1 says:
Similarly, a server MUST expand the payload of all UDP datagrams
carrying ack-eliciting Initial packets to at least the smallest
allowed maximum datagram size of 1200 bytes.
A server Initial containing just the ACK is not ACK-eliciting, or is it?
On the other hand, I understand that large server Initials verify that
the path supports >1200 bytes, which is also a QUIC requirement.
