I had nothing to do with creating them, and had never even even thought of the idea before. What I like about them is the ability to watch an animation play and turn keys on and off to see the difference (or do it while stopped on a frame). I also like that I can deactivate keys without losing them forever like with deleting them. But I’m all for modifications that would let them work better for people, like making them so they don’t turn on when they’re not supposed to, or even having the option of not using them.
By the way, don’t let the poll results fool you. Sure there are a lot of votes for getting rid of inactive keys, but there’s no option to say “keep them, I like them.” For all we know, there might be a lot of votes for “keep them” or “keep them but improve them.”
