But it is relatively rare to do that as well formed XML fragments can
usually be simply inlined into the containing XML.

But Xquery is not well formed. Even in cases where it looks well formed,
as my examples show, adding it to an XML document without quoting it in
CDATA will alter the meaning in many cases, however because there will
be other cases where it does not alter the meaning people will try to do
it anyway, using XML writing tools to produce Xquery with results that
are predictable in some technical sense but likely to be surprising to
most users.

It is not _just_ the encoding issue (although I think that is important)
it is the general use of XML syntax. Especially character references.

If Xquery is not XML it shouldn't use XML syntax.
