As for why the why is important: WikiActivity was going to be removed. It's a custom module that Fandom made with the hopes of giving new users a quick look at activity, that isn't as thorough and intimidating as Recent Changes. However, what it's intended for and how it's used are two different things. Many admins use it for quick glance policing: vandalism is easier to spot because added images and categories are highlighted. Because many users explained this use, Fandom is now reconsidering removing it. We don't have the final word yet, though.

So if you dislike a change, make sure you give good arguments as to why you think an aspect worked better before.
