Suppressors make shooting more user and bystander friendly, which is why they are mandatory in some countries. Also might be nice in a home defense setting, but on the street for CCW I would think they would be highly impractical. So, for me, the only reason I would see for a suppressor on a subcompact pistol is for "polite" range use, or simply so you can shoot without extensive hearing protection. On the other hand, there is always the cool factor, and why not? I doubt CZ will market one with a probably very low demand, but you never know.
