I noticed that the metadata overrides file is not up to date with extension support for 1.11:
https://github.com/quarkusio/quarkus-platform/blob/master/descriptor/src/main/resources/extensions-support-overrides.json
 
I've discussed it with hamadhan@redhat.com who is taking care of this matter today. Also maybe there is a problem with the process (doing only backport or something) since the `1.7` version was more up to date.
