Atleast we know that we will get one more use for them in one of the next updates when keep battles are introduced. TW said that they would use the whole scene there much more then before because the defenders retreat trough the streets of the town.
I won't hold my breath on this, I've had a quick look on some scenes, it would need a total rework of 90% of the actual content if they intend to do this without any transitions.
If anything, I suspect Keep battles will be transitioned just like Hideout battles, after the first battle finishes you're teleported in another scene, that it's.
