I see *large* variable length headers, in combination with complex parsing rules, as the problem.
(*large* variable headers) exactly, plus fragmentation
Fragmentation is not specific to IPv6, is it? And, as the fragment header itself is just 8 bytes (AFAIR, too lazy to check ;)) - I'd not classify it as *large* variable header.
and "ambiguities" wrt fragmentable vs. unfragmentable part and how headers point to the next one once there's a cut between them due to fragmentation. the, what we consider, "problem space" is much larger, unfortunately.
Has not RFC7112 addressed this particular problem? -- SY, Jen Linkova aka Furry
