The reasoning here is probably that when someone
does dir(C), they want to know what operations are
supported by *instances* of C, not C itself.
It makes sense when you think about it that way.

This is just another one of the ambiguitities
caused by Python lumping together class attributes
and instance methods in the same dict.
