Oh I totally agree that I think its not great for the game in terms of balance. As a dev, I do enjoy being able to make my own custom addons, especially as a healer. But I think a push towards less addons in the game will help its casual accessibility big time.
This is an issue even in Mythic+ where missing a single kick means you likely wipe your group and if its a pug they probably all leave the key afterwards (the latter is a separate community issue, but exists nonetheless). If Blizz in the future is forced to assume that most players dont have kick addons that tell them which party member has a kick up and a timer/alert to tell you when to kick the caster mob, then theyre also forced into improving the UI to help the players know that information without external assistance. Or even better improve the mechanics writ large so that arcane knowledge is less zero-sum when you dont have it.
