Please do! opam-nix is still being developed, and I'll update documentation as I do so. For now, I think the example for `buildDuneProject` should be relevant for you.
Examples were originally intended for prototyping the interface and testing the capabilities of the builder, and only then they became actual examples. I have refactored them to be flakes, so...

One idea would be to add `merlin` to the packageset (by adding `merlin = null` to the query) and then using `merlin` from the resulting scope in your `devShell`. It...
Not sure I understand the question.
