> they certainly have capability to review a trusted pasteboard copying predicate as I am suggesting

They do not have the capability to exhaustively check all uses thereof in a way that obviates the need for a user to consent to having you monitor their pasteboard.

They could develop it, expending significant resources on an edge-case for a tiny fraction of app developers, or they could ask the user for permission because the user has the context to expect this request (or to not).

They already do similar stuff like cross referencing applinks at .well-know/apple-app-site-association with the associated domains bundled in your binary.

What I'm suggesting is a predicate like only allow NSPasteboard access without prompting iff the predicate passes something like let predicate = NSPredicate(format: "SELF MATCHES %@", "^/.\\?var=.$")

I don't think you know what you're talking about.
