Windows will just populate the reverse zone as needed, if you let it, using dynamic update. If you have properly deployed BCP 39 and have anti-spoofing ingres filtering then you can just let any address from the /48 add/remove PTR records. Other OS's will follow suite. Alternatively you can delegate the reverse for the /48 to servers run by the customers.
