I'm generally in favor of adding more data structures to Python,
but I'm at best -0 on this. Besides being trivial to code and
questionably useful, a much better implementation could be
written using heap.

Maybe with a better implementation I would go +0, but I'm
hard pressed to see a case where this would be needed and
could not be trivially written.
