You are correct, When I try using the $ npx --node-options='--experimental-strip-types' eslint --flag unstable_native_nodejs_ts_config -c tests/fixtures/ts-config-files/ts/eslint.config.ts
(node:71533) ExperimentalWarning: Type Stripping is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
(node:71533) ESLintIgnoreWarning: The ".eslintignore" file is no longer supported. Switch to using the "ignores" property in "eslint.config.js": https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files

The
process.features.typescriptflag, which #19401 relies on, was added in Node.jsv22.10, meaning there currently is only support for>= v22.10.0.Manually parsing the flag to supportv22.6.x - v22.9.xis pretty cumbersome, so I would suggest to document support only starting>= v22.10.0👍Prerequisites checklist
