It doesn't. I wasn't commenting on your problem examples, just on some
reasons why 16-bit IDs are likely to still be workable, for reasons
outside the protocol space.

In the case of UDP traffic, I'd expect that protocols and their usage
will shift over time. As with the TCP over satellite type changes,
people will find better ways to get their data through the network than
giant fragmented UDP packets.

btw - how is UDP fragmentation addressed in IPv6?
