Support and Migration: ESL ESLint Deprecation Rules

⚠️ Deprecated: The standalone ESL migration / deprecation ESLint plugin has been removed and is no longer supported.

Use the integrated shared ESL ESLint configuration (with built‑in migration & deprecation rules) instead: ESL Shared ESLint Configuration & Migration Support

For an overview of all linting resources (ESLint config, Stylelint config, migration helpers) see the Linting & Code Quality index.
