Access the Content Collections names and configs from within an integration?

[severe wigeon]

Hi! I'm currently working on a free and open source CMS for Astro's Content Collections. It would be a web interface that would live parallel to your blog/website (e.g: at https://myblog.com/admin). Once authenticated, you'll be able to see all of your collections. And for each of them, you'll be able to create/edit/delete entries.

I would like to make that integration as simple as possible. Ideally, you would just have to run astro add name-of-my-integration and set the Astro output to hybrid or server. That's it.

I'm quite close to reaching that goal. My remaining problems are:

1. I need to list the collections names (aka, the keys of collections from src/content/config.ts). This would be used to list the collections on the CMS dashboard.
2. I need to get the config for each collection (to know whether it's a data or content collection, and get its Zod schema). This would be used to generate the forms to create or edit a collection's entry.

My current solution is to "pass" the entire collections object from src/content/config.ts to my integration using locals. I'm doing this using the following middleware:

import { defineMiddleware } from "astro:middleware";
import { collections } from "./content/config";

export const onRequest = defineMiddleware(
  ({ locals}, next) => {
    locals.collections = collections;
    return next();
  }
);

With that, I can use Astro.locals.collections to access the collection names and config from within my integration.

I was wondering if there is any other way of doing this? It's my first integration so it's possible I've overlooked something.
Alternatively, should I consider working on a PR to add getCollections() and getCollectionConfig(collection) to Astro's Collections API?

To better illustrate what this integration does, here's some screenshots. Let's start with the Astro blog starter.

You can connect to the CMS dashboard by going to https://myblog.com/admin. Once logged in, you see the Collections and the entries for those collections

I'll create a new blog post:
