I took a look at the haskell.nix code base but I haven't made any tangible progress due to the complexity involved, albeit it should still be completely possible from what...
I get ``` $ nix develop trace: No index state specified for haskell-project, using the latest index state that we know about (2022-02-15T00:00:00Z)! trace: To make project.plan-nix for hoogle a...
Most of the ecosystem has finally moved on to 9.2.4 with deep subsumption.
I wonder how much performance we're missing out on.

I'm not sure what a could way to detect this would be, @michaelpj has more experience with this.
With Plutus projects, it's very common to do `doHaddock = false` on various dependencies, and it seems to be related to this too.

With proper dynamic derivations it inherently can not affect evaluation times as it is done at build time. It is possible that Nix is slow at handling many derivations, but...
Sometimes you want to use `cabalProjectLocal` without `cabalProject`? This is just a plain bug, no?
