And since you won’t be able to modify web pages, it will also mean the end of customization, either for looks (ie. DarkReader, Stylus), conveniance (ie. Tampermonkey) or accessibility.
The community feedback is… interesting to say the least.
Frankly, I don’t trust that the end result won’t hurt users. This kind of thing, allowing browser environments to be sent to websites, is ripe for abuse and is a slippery slope to a walled garden of “approved” browsers and devices.
That being said, the post title is misleading, and that was my whole reason to comment. It frames the proposal as a direct and intentional attack on users ability to locally modify the web pages served to them. I wouldn’t have said anything if the post body made a reasonable attempt to objectively describe the proposal and explain why it would likely hurt users who install adblockers.
