It's more complicated than that.

iter(o) does (roughly)


At class definition time, if the class defines __iter__, a
wrapper for it is stuffed into the type's tp_iter slot.  If
it doesn't, NULL is placed there instead.

What *could* be done is, if the *meta*class defines
__getattr__ or __getattribute__, all the tp_ slots could be
filled with a special wrapper that calls the generic
attribute getter.  But that would be quite a coding effort,
and these classes would have pretty atrocious performance.

And making this work when you assign to __getattribute__ on
the metaclass would be a truly crazy piece of code.

Or the docs could note this limitation.
