    You are missing the point. If you have a big list of suspect phone-numbers you can put them into Signal and it will show all that have their phone numbers registered with Signal.

    Yes. That’s exactly what you get. A list of Signal users.

    That is a metadata leak and quite a significant one.

    Why is a user list in itself “a significant metadata leak”. You would need other information for that, like groups, contacts, online times or anything else. But you don’t get that, so I can only repeat my question: what is the problem with it?
