IDFA in JavaScript in light of ITP 2.1

It would be great to add a JavaScript interface to IDFA to Safari in light of ITP 2.1. It could follow the established pattern:

This would be a great solution for everyone involved. Essentially, organizations with multiple websites have had to try and use cookie/iframe hacks to replicate what IDFA seamlessly provides on iOS across multiple apps. With ITP 2.1 most of these web hacks will be broken. So we will be forced to jump through even more hoops using requestStorageAccess() to again try and mimic what IDFA does out of the box. A homegrown solution will always lack the global user control provided by the IDFA integrated into the os, and therfore be inferior.


With IDFA, a tested precedent is already established. If we could access it via JavaScript in Safari a lot of concerns would be resolved.
