UUIDs as object identifiers (maybe string based?)

I know that there are some tickets around, but honestly, its quite annoying to not have this key feature of a database implemented. I saw, that there were some efforts in 2017 (thats 4 years ago btw.) but nothing changed since. So instead of only having Long as an id primary type, i also would like to have String and UUID. I know, that there are maybe some performance impacts with that, but that should not matter, since its the responsibility of the developer to choose the correct id types.

Use case scenario for UUIDs:
Distributed systems, where you identify your entity by its globally unique UUID, and you dont want to deal with internal system ids and the global UUID.

Beginne mit der Überprüfung der bestehenden Unterstützung für Primärschlüssel und Objektbezeichner und suche dann die im Issue referenzierten früheren Tickets und Arbeiten aus dem Jahr 2017. Der Umfang muss klären, wie String- und UUID-Bezeichner funktionieren sollen und welche Kompatibilitäts- oder Performance-Einschränkungen gelten. Der Abschluss sollte vereinbartes Verhalten und Abdeckung für beide Bezeichnertypen umfassen.
