No, it's clearly not strictly required.  One could clearly put the
identifier in the transport header, for example.  But then it's not there
for firewalling, which *would* be nice, or for mobility.

It's a design choice, and it's a very nice and clean one.

I asked exactly the same question when I first heard the proposal, but it's
grown on me over the years and I'm now convinced that it's in fact a very
good choice.
