"Keeping traffic safe", etc. is not the reason they are moving all the wikis, they just mean they are moving only this the initial group of 3200 sites as a sample to monitor that the traffic to just those 3200 sites is safe, etc., since they are also changing to https at the same time. The only reason to change the base URL is to be complete the "fandom" rebranding. I think this choice of rebrand is silly and as other pointed out they are just trying to own the word "fandom" to steal traffic from other sites for that lean, mean, mean green.
