Suggestion

@typescript-eslint/eslint-plugin-tslint is an ESLint plugin that allows running TSLint rules within ESLint. It's made to help folks migrate off TSLint towards ESLint.

eslint-plugin-tslint has existed in this monorepo for many years because that was a convenient way to keep it maintained alongside our other packages.

But, we keep synced package versions (for good reason - see #7521). So eslint-plugin-tslint has been getting version bumps steadily for years ... despite no new issues being filed on it for quite some time. A query for relevant issues with label package:eslint-plugin-tslint shows that we haven't had anything come up since 2020.

Keeping the package around is also a maintenance burden. For example, in #7752, its unit tests are failing with EXPERIMENTAL_useProjectService enabled. I really don't think we need to test the case of someone running with eslint-plugin-tslint and the new project service.

Proposal: let's make a new repository for eslint-plugin-tslint.

• It won't need to automatically publish new releases weekly with the rest of our packages.
• Its only dependencies entry is @typescript-eslint/utils, which we can switch to a ^ version matcher.
• We'll still be able to actively maintain the repository if anything comes up
