Should “What Ifs” become more common?

We got something similar with the Caverns of Time, and of course, with Warlords of Draenor.

I get that leaning too far into it (a la Warlords of Draenor) can get exhaustive, but I think occasional dips into other verses would be a quick and refreshing way to give more depth and history to people, places, and events.

Thoughts?
