We have a situation where we want to override an input’s input, but
not the input itself. It looks something like:
inputs.a = {
type = "github";
owner = "example";
repo = "a";
inputs.b.inputs.nixpkgs.follows = "nixpkgs";
};
The problem is that Nix thinks we are overriding "b", when we are
really only wanting to override one of "b"’s inputs. The flake url
should remain the same, but with existing behavior, Nix assign "b" to
be an indirect input, and ignores the "b" from "a"s inputs. We want it
to behave more like the "follows" and not treat it as a full override
of "b".
