Honestly, it really is not the language that’s the problem. While there are a few cases where it can trip you up at first, you wouldn’t be singing package descriptors even if it were Python — it simply has a business domain which is non-trivial. This non-triviality and organic growth show on the standard library of nix packages, but I fail to see how a lisp language or whatever be immune to it, besides having learned from some early abstractions mistakes.
And one might even argue the opposite, a DSL made for creating packages may well be better. Especially that plenty of package descriptions are basically reads like JSON.
