Was thinking about this the other day: was there any data that users don’t like a default <div> animation? <table> ones yes, they are godawful, but <div> animation wasn’t that bad on the second thought. It’s not like we don’t use animations anywhere, so it was a nice addition to .mw-collapsible while it lasted.
No, I didn't log all the times that ppl complained about them. My summary of that was mostly anecdotal. However, even if we were to readd them, we would do so with CSS animations at the very least. simplifying the code before recomplicating it would make sense in that case too.
