Well, a marquee (not necessarily the HTML element per se but the design element) is often used on news sites/forums, at least amongst those I visit currently - it's used there as a news ticker.

I could go on and argue that it's far more common than a toast (which I barely see at all. Than again I don't like PWAs and try to avoid browsing from mobile when I can). But the sites I visit are not remotely representative at all, so I could well be wrong. I guess the sites you visit are also not remotely representative.

IMHO, The fact that <marquee> was added and supported for so long (despite 'deprecation') is the best indication there's some demand for it, a better indicator than our browsing habits. Marquee is definitely more distinctive than <toast> is from other elements and better supported. So IMHO there's a much better case for including it compared to <toast>.

P.S. The browser provided date pickers are so poorly designed and inconsistent I wish they didn't provide them at all. It's something I always override when I have time to do it.
