The html5 parser special cases unprefixed svg and mathml elements
(only) so unless I misunderstand what you meant above then these two
items are contradictory. There are no "standard prefixes" for svg and
mathml, if you want to make an xhtml document work also in the html
serialisation then redefining the default namespace is the only option
supported by the curent draft.
