You can just use ghcup and cabal. The cutover you're nix-style cabal builds has happened and they are excellent.

You can even just use ghcup and cabal but work against a Stackage LTS snapshot for added ease.

If you end up using Nix in the future, barely anything will change for you if you start with bare cabal. It's additive, not a replacement.

Same goes for if you use stack as an enhancement, although a big appeal of stack is its own CLI.
