For me, the primary interest here is AP launching a watch with a full ceramic case and bracelet. And interesting that they chose to do it with the perpetual calendar complication.
I am not certain I see this filtering to other watches. As AP has stated how time consuming the material is to work with, maybe a higher price point piece like the PC makes sense for it.
When I look at the 15202 on my wrist, I would not change it for an all black model. That is just not this watch.
