 * "I'm curious as to why prior to this post, it already wasn't showing up as an option for a lot of wikis?"

This was mentioned in a Technical Update many months ago (not going to waste the time to find it again, someone prior to you asked the same question). Existing wikis using the Hero Image could keep using it but no other wikis could use if after it was no longer open to being enabled.

One of the reasons I've heard from Staff (back when there was discussion, probably on the same blog) is that the Hero Image affected advertisements. There's probably other reasons. As with the other labs, you shouldn't expect them to always be supported. They are in beta after all.

Those wikis using them will likely just no longer see them.
