It is not a bug, because none of the conforming features of HTML5

Same goes for any attribute name beginning with four z's, or
containing the sequence 'banana'; none of them are required by any
particular spec, yet removing them would be somewhat cavalier.
The difference is that "zzzz" and "banana" are XML 1.0 4th ed. plus
Namespaces NCNames and, thus, are permissible as XML local names.
"xmlns:foo" is not an XML 1.0 4th ed. plus Namespaces NCName.
But I note that you say "in non-browser apps"; are you saying that
attributes beginning "xmlns:" would be preserved in an HTML5 browser?
They'd be preserved, but their namespace URI and local name would
differ from the XML side.
However, for many other things, there isn't a (bogus) claim that
you only
need to add five attributes or so and that's all. RDFa involves a
countably
infinite number of attributes that are of the most problematic kind.
Ah...the bogus word again. You certainly have a rapier-like debating
style, Henri...no mistake.
Of course, whether something is bogus or not is exactly what debates
are supposed to prove, so throwing the word around adds nothing.
Is it in your assessment correct (aka. non-bogus) to advocate RDFa as
merely adding six no-namespace attributes to (X)HTML?
I claim that RDFa adds six no-namespace attributes *and* a countably
infinite number of attributes of the form xmlns:foo to HTML.
The latter happen to be different in HTML as it exists and XML
+Namespaces as it exists meaning that they need special care compared
to the six attributes. Therefore, the continued focus on the easier
part while sweeping the more problematic part under the rug, even if
sincere, gives the appearance of trying to sneak the more problematic
part into HTML.
