Not only is it still a thing, Google itself is a major culprit of it. Seems like every new experiment they release is “best viewed” in — or worse, “requires” — Google Chrome.
EDIT: So it does! The last reason I was keeping Chrome as my default (so Meet calendar invite links would work) is gone.
Great response from Alex Russell, but it's clear that the sentiments of the Chrome team aren't translating into policy elsewhere in Google, or we wouldn't be dealing with something like this every few months.
