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

I propose the addition of lazy loading support for rule definitions. As the number of rules grows, it becomes increasingly inefficient to load them all at once. Currently, all rules are loaded eagerly, which can lead to unnecessary memory usage and slower startup times, especially for configurations that use only a subset of rules (e.g., non-type-checking). Additionally, the lack of this mechanism breaks the lazy loading already implemented in the ESLint repository - all rules in the current repository that use the getESLintCoreRule utility eagerly load core rules.

Additional Info

ESLint Config

importtseslintfrom'typescript-eslint';exportdefaulttseslint.config({files:['**/*.ts'],extends:[tseslint.configs.base],});

eslint ./index.ts --debug

Expected Result

no eslint rules loaded
