I suspect the rationale was something like "make it simple for the first
version and see what else is needed later", but I agree that the extra
"simplicity" doesn't really provide anything useful.

It also forces a behavior for default namespaces defined by @namespace
(they don't apply to the stuff inside :not()) that may or may not really
be ideal.

Those aren't equivalent.  The former is equivalent to
:not(foo), :not([bar]).
