The person writing this has to repeat frequently that they're OK with the <toast> element; it's quite funny how hard they try not to upset people.
But their view of the situation is completely correct; just because this one feature might be useful (heck, when Microsoft dumped XMLHttpRequest on us that was incredible too), doesn't change the fact that we're now living in a web where Google does whatever it wants, adds whatever it wants to Chrome, and the web is at its mercy. If they wanted to add <blink> it'd get added and supported, and other browsers would have to follow lest they become incompatible.
There's not really much of a difference between the web today and the "Best viewed in IE" web, and that's sad. There's a difference in developer goodwill, and of course things aren't as buggy as they were back then so it overall doesn't feel like you're "stuck" with Chrome like it did with IE, but... you are. You're just OK with it.
