No, seems to be just the same in HEAD :-(

Yeah, it does, or at least the implications of not doing so would amount
to a ground-up redesign, as well as moving a lot of cycles out of rule
creation and into every rule use.

What I would have expected to happen is for the ALTER TABLE to throw an
error telling you it couldn't cope with updating the rule, and that
you'd need to fix that manually.  There is such a test involving views;
not sure why it's not catching this rule.
