So we all agree that 'variable length is OK as long as our hardware can look deep enough'? And what people are complaining about is exact number? Which we do not know yet for IPv6 EHs?
Agreed, variable length *by itself* is not the problem.
I see *large* variable length headers, in combination with complex parsing rules, as the problem.
(*large* variable headers) exactly, plus fragmentation 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. thanks Enno
