Not sure how the protocols themselves help, but at least for now, we still have things like content blockers and extensions for mobile web browsers. Native apps have more freedom to do whatever they want, and they do it more opaquely. I guess the only thing that comes close to a web browser content blocker for iOS native apps is piping your traffic through one of those ad-blocker VPN apps like Lockdown, which sucks. Of course, nothing compares to the amount of insight you have into websites on a desktop web browser where you can open a networking tab in the dev tools.
