This will never catch on in the building industry unless it can demonstrate significant time/cost savings.

If it does get adopted, those time/cost savings are going to be skewed towards the initial building phase, and renovation will get more expensive. Sure, a renovator can remove the surface layer easier, but then they either have to resurface the existing one, or buy a new one, both of which are guaranteed to be more costly than resurfacing ordinary drywall (or just papering over the existing wallpaper).
