Why isn't the convention in nixpkgs that `hash` is overridable too (along with version) so package overrides would actually be useful?

Hey hey,

I’ve also run into this before, and just saw this other post: Isn't this a nix antipattern? . They suggested to maybe pass version as an input, although if multiple hash values need to be updated, passing them all separately would be quite annoying…

A standard could be to add a single easily overridable attrSet like:

pkgMeta = { 
  version = ...;
  hash = ...;
  npmDepsHash = ...;
  ... # other versioning/hash values here
};

and then have src pull from there? This could be put under passthru, or passed as an input maybe.
