I believe that using Sequence ABC as mix-in is recommended when implementing custom sequence.

But mixing-in it violates "should only provide __reversed__() if they can
 provide an implementation that is more efficient than the one
provided by reversed()."

Defining __reversed__ in Sequence ABC also means that classes doesn't have
__reversed__ aren't Sequence. While not implementing it is recommended
for most cases.
