The actual goal is probably that Google and others prevent ad-blocking. WEI itself is not meant as a fingerprint, but with unblockable ads comes unblockable tracking (not that I personally care about tracking). Like, look at YouTube on iPhones, they blocked background playback in the app and even got Apple to block it in Safari in iOS update 10. They don't need WEI to keep the vast majority of users away from obscure alternative OSes, but as a side effect those would be impacted.
