@Gargron it's like language. Or any evolutionary system. An ecosystem develops itself. Good bits from the old survive and thrive. Good bits from the new come to dominate. If there are features that really need to be excluded (embedding videos) then people will get the hang, or it'll start being enforced.
CWs are just tedious to me, it takes as long to scroll past one as it does to scroll past the toot itself, given their choice of font. But it's changed my behaviour knowing they are normal.
