Support for project: true or useProjectService: true ?

[Samuel-Therrien-Beslogic]

Hi! I'm wondering if the resolver currently or plans on supporting project: true like https://typescript-eslint.io/packages/parser/#project ?

As well as plans to support useProjectService once out of experimental phase (currently experimental as EXPERIMENTAL_useProjectService https://typescript-eslint.io/packages/parser/#experimental_useprojectservice ) which solves a few more issues (including performance) with finding the tsconfig.

Is there any guide/docs about how to use/implement projectService in a third-party library (eslint-import-resolver-typescript in this case)?

Sorry I'm not that knowledgeable about how that would work, I suppose the best place to ask would be https://github.com/typescript-eslint/typescript-eslint/discussions , maybe this discussion typescript-eslint/typescript-eslint#8030 ?

Edit: I've forwarded the question: typescript-eslint/typescript-eslint#8030 (comment)

Due to the previous performance degradation (up to 50% slower) with parsing, I doubt the non-isolated parsing would do any good with module resolution. For now, I'd prefer not to do module resolution with type information unless the typescript-eslint team has other details that I don't know.
