HTML parser is already complex enough that using a simple rule of always falling back to HTML if element names are ambiguous may result in a better overall developer ergonomics.

Possibly, dunno.  I could go either way.  Consistently resolving
ambiguity in one direction could be simpler, but so could resolving in
favor of the massively-more-likely one.  Spec/impl complexity isn't
really of concern here; impls would need an explicit list of
elements/namespaces anyway. The spec could possible get away with a
blanket statement, but that opens up the possibility of ambiguity,
like <image> (which should clearly be SVG, despite the parser turning
it into <img> for you).
