It would seem unfortunate that an XHTML5 processing tool (not a UA, but just something that wants to do something with the content) can't just be an XML tool and would seem to ruin the whole point of it being XML (IMO).

XML tools work with XHTML5. You just aren't required to validate XHTML5 using a schema-based validation system. You may use a schema-based XML validation system if you want to, but you should be aware that no schema language can capture all the conformance requirements of XHTML5.

XHTML5 isn't substantially different from SVG 1.2 here. The schema offered for SVG 1.2 doesn't capture all the conformance requirements for SVG. For example, the schema doesn't check that xlink:href values are valid IRI references.
