I would think so, but thought I would double check with all you experts!

Is the sheathing a necessary component of an acoustically rated assembly? Is the sheathing a convenient way to enclose an above ceiling plenum space or seal off an HVAC zone from another one or untreated space? If not, it isn't really serving any purpose. It might even be the spark that starts a undesired VE dialog to replace the mechanically anchored stone system with a thinner, mortar set stone system.

If engineered to be used without, I suspect no problems (other than those already pointed out.)
