I believe the following additions could be made to the Powerset module :

  1. A ∈ₚ operator that produces an hProp for x ∈ₚ A rather than a general type
  2. Binary unions and intersections
  3. Indexed unions and intersections
  4. A separate type for "inhabited subsets"
  5. The complement of a subset

While these are easy to define I found consistently needing these and believe others could benefit from it too.

I'd be happy to drop in a PR.
