New submission from Devin Jeanpierre: For sequence __contains__ and other scenarios, identity is checked before equality, which I've heard is so that "for x in y: assert x in y" doesn't ever fail with an AssertionError (even with NaN and so on). This is not the case for collections.abc-based sequences, which is a jarring inconsistency.
