So you think that it's within scope of the SVG spec to define the
handling of non-namespaced elements?  Or are you proposing a different
way of making the same thing a requirement?  That's unclear given your
later statement:

Such a document is invalid (and therefore non-conformant) since it
doesn't meet the validity constraint that the DOCTYPE declaration match
the name of the root element [1], since there is no root element.
(I'm not sure whether that's the point you were trying to make.  But it
was the reason I cited that section.)

However, the document not being a conforming SVG document doesn't tell
implementations how to handle the document, so it doesn't help
interoperability, as far as I can tell.  And this does seem to be a real
interoperability problem.
