Seems that also makes sense in the scope of this proposal.

I think that is reasonable, it is ~= to the same as Map except the key check, so we can look to add it after the meeting this month. The semantics of the algorithm landing would make it a bit easier to ensure we don't have to discuss and track 2 algorithms yet.
