For some reason `nix flake lock` is trying to download stuff; I need to fix this. Marking the PR is draft for now.

> We could add it as an optional feature, but I don't think it is very useful outside of nixpkgs. Well, a bunch of tools do use longDescription. For eg....

Here's a real-world use case, if maintainers are looking for one. I have [4 example flakes in this repo](https://github.com/srid/nixos-flake/tree/master/examples), and would like to (after adding a `flake.lock` to each) a...

Another example: [services-flake](https://github.com/juspay/services-flake/tree/main/.github/workflows) which currently updates 4 lock files: This ends up creating 4 [PRs](https://github.com/juspay/services-flake/pulls?q=is%3Apr+%22Update+lock%22) every week:

The first issue I faced in the wasm frontend when using `typetag`: https://github.com/dtolnay/typetag/issues/8

Is there a reason why this cannot just be: ```haskell type Attr = Map Text Text ``` i.e., why not put both `id` and `class` in the attribute `Map`?

[`Data.Map.Ordered`](https://hackage.haskell.org/package/ordered-containers-0.2.2/docs/Data-Map-Ordered.html) from ordered-containers? > An OMap behaves much like a Map, with mostly the same asymptotics, but also remembers the order that keys were inserted. All operations whose asymptotics are...

@sol I'd like to see this happen as well. It will help projects using Nix. Because of reproducibility of nix, I can pass a hashed path (from store path) to...

Failing this, I'd workaround this by creating a wrapper `hpack` script that injects the defaults on the given `package.yaml` before invoking the actual `hpack`. But that'd be pretty hacky.
