While WEI is thankfully cancelled, it’s not entirely cancelled… They’re planning on making it available still in WebViews with the intention that websites can check if a malicious Android app is trying to do a phishing scheme.
Seems like such a niche “security” feature… what are they really trying to accomplish here? Something seems fishy to me
You’re completely wrong.
This means that they will implement it, and then it’s only a tiny change to make it available everywhere if they decide to do so later.
The option alone also now also allows people to build stuff that will only work in those WebViews, rejecting to work without the integrity check, which is already a huge loss.
Can you give a concrete example how this would be a huge issue? A webview is part of an app, which is already a closed system. If a developer wants to, they can already build their app using native UI with integrity checks. Now they can do the same when using webviews. It really has none of the implications it would have for browsers.
