[Docs] Following #52, it'd be good to have a decision doc for licensing. Even if it's just "we need / want to use the same as existing ESLint licenses".

There was no decision made. The OpenJS Foundation says any new projects must be licensed under Apache 2.0.

Is there a source that can be linked?

Linked from where?

And I have no idea. We've been part of the foundation for a long time and this was communicated early on.

There might be something somewhere in https://github.com/openjs-foundation if you feel like going on a search.

Linked from where?

Proposal: a decision doc, for visibility?

Following #52 and #73: I don't feel able to review this file without understanding how this is meant to play with @types/eslint over time. Is it intentionally different? Have the tradeoffs been discussed somewhere?

We weren't consulted on the creation of @types/eslint, so I consider those to be non-canonical types. As we move forward, we'll be creating types the way we want and using those. Maybe @types/eslint will get smart and start importing our types to flesh out the package, but either way, I'm not going to worry too much about it.

non-canonical types

Practically speaking, those and typescript-eslint are canonical types, as those are what the entire community uses at the moment. If the decision is to explicitly not attempt backwards compat, sure, that's a reasonable decision - but I don't think they can be ignored in decision-making summarily.
