We've decided to wait on this until some further verification lemmas have been written for Std.HashMap. These are now being actively worked on, so hopefully it won't be too long.

Those additional verification lemmas about HashMap.toList and HashMap.fold have now landed, so as far as I'm aware we have feature parity with downstream libraries based on the old HashMap, and I would like to proceed.
