OK, all,

So let's try it this way:

- standards people on this list claim that 8200 already allows silently
ignoring HBH options

- ops people on this list claim that most routers already do this

So if you accept the items above, then why exactly is this document
needed at all? The standards already support it and operators already do it.

It clearly isn't needed, just as clearly as it isn't driven by security
issues.

So I would conclude that whether we agree on the logical path, we have
come to the same conclusion - drop this doc and move on.
