Andrew Svetlov added the comment:

After brief looking sources I figured out it can be solved by adding setters for __isabstractmethod__ to classmethod/staticmethod objects.
It can be done, I'll try to make a patch.

For property situation is worse: property is abstract if any of getter/setter/deleter is abstract.
Which object attribute should be set for setting __isabstractmethod__ for property?

We can make the rule: abstractmethod for classmethod/staticmethod/property should set descriptor as abstract, not functions behind it.

I'm not sure is it true solution but I like to try to make a patch for that.

Anyway, the patch for describing current behavior in the docs is welcome.
