The odd thing about this draft is that <optional/> is mandatory. An
artifact of how one writes these things...

Right, I've gone for:

OLD: Clients SHALL ignore such advertisements.
NEW: Clients MAY ignore such advertisements, and are encouraged to do so.

So in RFC 2119 terms, it's truly optional, but for reasons other than
interoperability we're encouraging people to avoid the request.

Also, later on, I've added:

NEW: It is important to note that there is no value in performing this
request, and New clients are expected to elide the request when the
<optional/> marker is present.
