I originally also had some hope when the dev first delayed it but now, you shouldn't even expect the GYM DLC to be changed at all whenever it gets released.
Since, based on previous progress reports, dev said it's not going to be a complete rework and the concept will remain the same. Or maybe they might just end up releasing it as it is as they don't seem to have any idea of what changes to make(feedback channel, hello?? what's the point of it?) so, the dev can't even answer your question at all.
Lovense Integration for a 2D game with no actual sex animations doesn't make sense either, I don't even see the appeal of using it for those 3D VNs with POV animations either, to me, it only makes sense to use it for an actual 3D game especially with VR for full immersion.
