@ekr I believe it is dual purpose:

>From the current transport draft:

>The payload of a UDP datagram carrying the first Initial packet MUST be expanded to at least 1200 bytes, by adding PADDING frames to the Initial packet and/or by coalescing the Initial packet (see Section 12.2). Sending a UDP datagram of this size ensures that the network path supports a reasonable Maximum Transmission Unit (MTU), and helps reduce the amplitude of amplification attacks caused by server responses toward an unverified client address; see Section 8.
