From a transport perspective, there is one minor issue:
Section 7.3 provides a motivation for using a path MTU for IPv4 of 576 bytes.
The motivation refers to the requirement that a receiver is capable of
receiving IPv4 packets of that size, however they can be received fragmented.
While it is acceptable to use 576 bytes as the minimum PMTU, the motivation
does not hold.
