My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

Forking #10383: right now, if you want to use the new Project Service, you have to go through @typescript-eslint/typescript-estree. That's a rather large package with large dependencies: the catch-all @typescript-eslint/utils, ts-api-utils, etc.

There are two use cases where I think folks would want this split out:

• If another linter wants to use the Project Service itself (😍!)
• Enhancement: Move RuleCreator into its own package with fewer dependencies than utils #10383 (comment): starting to split up the typescript-estree and utils packages so we can provide more granular exports for RuleCreator & other utils

Additional Info

I've prototyped this locally and will send a draft PR soon edit: #11182. I think we'll also need to extract out a @typescript-eslint/tsconfig-utils package to share:

• CORE_COMPILER_OPTIONS
• getParsedConfigFile
