I've been trawling through various standards trying to identify sane
extension header combinations myself.
I've come across a couple of problematic standardised options already
defined that don't appear to have individual length limits below the
overall generic limit of 256 octets per option (derived from the "Opt
Data Len" field being 1 octet), so limiting the overall header length to
256 octets could have direct impact on those.
PadN (of course)
The lineID option rfc6788.
The Routing Protocol for Low-Power and Lossy Networks (RPL) Option rfc6553

Neither of these should appear outside of limited domains. The Line
Identification option passes from the Access Node in a broadband
deployment to the edge router (BNG) and goes no further. The RPL option
is used only inside of RPL networks.
