+Feature: #98394 - Introduce event to prevent downloading of language packs

+    <?php

+
+    use TYPO3\CMS\Install\Service\Event\ModifyLanguagePacksEvent;
+
+    final class ModifyLanguagePacks
+    {
+        public function modifyLanguagePacks(ModifyLanguagePacksEvent $event): void
+        {
+            $extensions = $event->getExtensions();
+            foreach ($extensions as $key => $extension){
+                if($extension['type'] === 'typo3-cms-framework'){
+                    $event->removeExtension($key);
+                }
+            }
+            $event->removeIsoFromExtension('de', 'styleguide');
+        }
+    }
+
+Impact
+======
+
+With the newly introduced event, it is possible to ignore extensions or
+individual language packs for extensions when downloading the language packs.
+However, only language packs for extensions and languages
+available in the system can be downloaded. The options of the `language:update`
+command can be used to further restrict the download (ignore additional
+extensions or download only specific languages), but not to ignore decisions
+made by the event.
