I agree "full-fledged build system" is not a possible immediate goal. But an EDSL for expressing cabal projects (as they are today) would still be in scope of your proposal—and I thought you liked the idea (see quote below). Using the earlier options: option 3 is not in scope of this thread, but option 2 is, with the only danger that the design space is so big to present a challenge.
Yeah I like the idea of using Haskell for configs but perhaps in a different problem space e.g. in a build spec. See the quote from my earlier quote below, sorry for the confusion :-) Yes, maybe option 2 might work for package specifications but sounds pretty hairy to explore for this use case alone, unless we have other motivations.
Quoting from Harendra Kumar's earlier mail:
If we have to express not just a package specification but a sophisticated build configuration, we need a real language. Expressing conditionals, reuse etc becomes a compromise in a purely declarative language.
