i don't think that's what you're describing here.

i think you've conflated A/B testing with user-profiling. you will obviously know if a campaign has been "effective", if sales increase. you absolutely do not need to uniquely identify a user to do this (which is what happens today).

as stated, apple don't want to remove it, merely make it opt-in. and if the end user isn't opting in, they probably don't want it.

This is simplifying marketing too much. You’re likely to run concurrent campaigns on different platform, Facebook, Instagram, Google Search, Twitter, etc.
Marketers would like to understand what campaigns and what medium helps drive sales/installs. No need to waste money on Twitter ads if it turns out no one actually ends up buying.
This is easily managed by changing the url based on the source of traffic (e.g., the omnipresent ?camId=foo on so many links). Heck, back when I published a magazine, I did this in analog form by using slightly different addresses for mailed in subscriptions (adding a Dept S to the address for the ad in Step by Step, Dept H for How Magazine). It doesn't take intrusive user tracking to be able to measure this sort of thing.
There are no URLs in app installs. The ad links to the iOS app store, and Apple does not give you any information post install on where the source came from.
Most ads don't link directly to the app store, but instead send you through a tracker site which logs the click before forwarding you to the app store.
