> The demand that "I want my browser to be exactly the same speed as it used to be, but also support all these new features" doesn't seem like a reasonable engineering ask. Certainly. What does sound like a reasonable engineering request is "I want my browser to be roughly the same speed as it used to be when using these same features that it used to have". Some speed penalty is obviously to be tolerated because of the larger infrastructure (I was about to say boilerplate, but let's keep it civil, there's a legitimate need for it) required to service the extra features, but I think I'm being reasonably lenient even here, considering that this larger infrastructure runs on vastly, vastly superior hardware.
