Shouldnt this be all builtins.derivation options?

The actual interface of builtins.derivation

builtins.derivation :: {
        name :: String;
        outputs :: [ output @ String ] ? [ "out" ];
        builder :: String;
        system :: String;
        args :: [ String ] ? [ ];
        ${additionalArg} :: a;
    } -> Derivation

builtins.derivation will accept anything that it can implicitly coerce into string.

such as:

• list
• path (is a syntactic wrapper around string)
• string
• number
• etc

Side note:

even the outputs list is coerced into a single string. internally this is also why a list like outputs = ["my app" "pkg" ] would yield 3 outputs. Also this would fail because one item of the list MUST be "out"
