Workaround, if people need it:

import { fixupPluginRules } from '@eslint/compat';
import * as eslintPluginTanstackQuery from '@tanstack/eslint-plugin-query';

export default [
  {
    plugins: {
      '@tanstack/query': fixupPluginRules(eslintPluginTanstackQuery),
    },
    rules: eslintPluginTanstackQuery.configs.recommended.rules,
  },
];
