I personally think the XQuery Flagger is unenforceable and therefore
should be removed.

We cannot stop someone shipping a product that supports two languages,
one of which is XQuery and the other is NotXQuery. Such a product can
claim conformance. The fact that the language supported by NotXQuery is
actually XQuery plus extensions, with no flagger, cannot alter the fact
that the product as a whole is conformant. The XQuery specification
cannot impose any constraints on the behavior of a NotXQuery processor.
