Basically, Fragmentation, as specified in RFC-2460 (IPv6), solves the

I doubt if it is useful at all.

It's exactly what lets encapsulation tunneling occur and reoccur at will.

I.e., once you split a 1500 byte packet into 1280 and 220 and
encapsulate each of the results, you get to do it again.

Without fragmentation, arbitrary recursive direct (IP-in-IP) tunneling
is impossible.
