 Here is another example where projects tagged with 'stage:end-of-life' are not allowed to be used as the scope for a commit.
 
 In your .commitlintrc.js file:
 
 ```javascript
-const {
-  utils: {getProjects},
-} = require('@commitlint/config-nx-scopes');
-
-module.exports = {
-  rules: {
-    'scope-enum': async (ctx) => [
-      2,
-      'always',
-      [
-        ...(await getProjects(
-          ctx,
-          ({tags}) => !tags.includes('stage:end-of-life')
-        )),
+async function getConfig() {
+  const {
+    default: {
