I agree with that --- consider that you couldn't actually promise that the sequence hadn't been dropped by the time the answer is returned, anyway, unless you take out a lock on the sequence first. Which doesn't seem like a behavior that is wanted here.
The only objection I can see is that it arguably doesn't obey sequence permissions: you need SELECT on a sequence to see its currval(), whereas lastval() would return the same information without an equivalent permission check.
