Essentially the permutation are, I think: {'unadorned'|abc.abstract}{'normal'|static|class}{method|property|non-callable attribute}.At the abstract level, a property and a normal, non-callable attribute are the same thing.
They are from the instantiation perspective but not from the subclassing perspective. From the subclassing perspective, it's the difference between:
class Foo(object): @property def bar(self): ...
and:
class Foo(object): bar = ...
If an abstract property were to be answered by a simple assignment, then the "read-only" trait would be lost.
