I'm not talking about passing monitors through. I'm talking about having multiple virtual monitors in your field of view.
A shitty virtual 1080p screen taking your entire field of view is not even vaguely capable of being used for productivity purposes. It's not remotely close. The whole point of multiple physical displays is to have a meaningful amount of information directly visible at once.
Of course they did. It doesn't take any kind of abuse of the browser to do that. It's all on the website side and everyone does that.
Ban most data gathering websites do. But this has literally zero to do with the browser.
