Correct, I wanted to get comments on the whether the approach was
acceptable before finishing it.

Yes, if they want a hash table with specific parameters.

I think it has the advantage that the conversion function doesn't have
to know about all the possible parameters involved in hash table
creation.  Therefore the interface is simpler.

No, but I think it could be easily added.

I meant it as a variant on `map--into-hash-table', so it uses the same
naming convention.
