It seems a bit weird to take over if the client explicitly wants to download, and also weird to then go ahead with the download?

I agree. But we can't nicely cancel the download at this point. Ultimately, we'll have a separate download client or logic that doesn't navigate.

Or a separate policy type?

Actually, it sort of works if I ignore the download!

I originally considered a new policy type, but this one is actually set from Safari. I'll have to do something else for WKWebView clients.
