hedgehog VS smallcheck

I've had some PRs open on hedgehog for one and two months respectively. It looks like the maintainer isn't currently very active, which is fair enough. This isn't about criticizing him, and I'm not trying to take over the repo.

Testing libraries like hedgehog often run tests in parallel, so you may find related issues to work on.

Haskell has QuickCheck and Hedgehog, and dotnet has both as well. F# is favored, but there's C# interop.

Using laziness to avoid generating parts of an expression until it's needed is a really nice idea. The LazySmallCheck package[1] took this approach, but was limited in the types of data it could produce (e.g. it couldn't generate functions). This was extended by LazySmallCheck2012[2], but that seems to be unmaintained and doesn't work with more recent GHC versions.

(Note that these are named in reference to SmallCheck[3], which takes the approach of enumerating concrete values in order of "size"; as an alternative to the more widely-used QuickCheck[4], which generates concrete values at random, and tries to "shrink" those which trigger a failure)

Could you compare with https://hackage.haskell.org/package/smallcheck in particular the smallcheck ability "to verify properties for all test cases up to some depth"?
