Safari is planning to use ML to detect click_id type of query parameters and strip that from URLs. That's just poor execution and business destroying. PCM restrictions are horrible too.. we have to design the link so it stays within safari's specs:
> With an ad-click, an 8-bit ID can be transmitted (a number between 0 and 255, i.e. 256 possible values / campaigns) - per domain > For a conversion, a 4-bit ID is transmitted (a number between 00 and 15, i.e. 16 different types of conversion) - per domain
Not to mention Chrome and Firefox has other ideas, each different on how their PCM will be integrated. Other than the mega corps, noone is benefitting from this privacy enhancement. Just more work to adapt.
