Will this address the fairly common data design problem where we
need to ensure that a given value is unique across several tables
(possibly siblings, possibly not)?
That would be where the provably-distinct part comes in, so yes.
That assumes you can provide some provably distinct test. In the general
case I have in mind that isn't so.
