[BLOCK QUOTE].

I'm not sure I understand your question, so I'll just answer broadly. Basically, there's an include mechanism for these GDPR comments, but you can't include something from another repo. Since both repos refer to the same fragment, both repos have to declare it.

Why have a reusable fragment for a single property? I'm pretty sure there used to be multiple and, I assume, there might be multiple in the future.
