There is a plan to rewrite the spec, but not in this draft.  The
existing deployed base meant that no meaningful changes to the
protocol under the current option code could be made without
significant pain.  There is no will among the providers currently
using it to assume that pain.  So yes, this draft is just a cleanup
addressing the existing implementations.

I don't see language in the current draft that makes a whitelist a
requirement.  The language I do see doesn't even use 2119
capitalization, so it's even softer than usual.  If there is a
statement in there that you think mandates whitelists, I am amenable
to modifying it.  I see that as an endpoint operational policy issue,
not a core protocol issue.
