Spoke to my local Porsche Service Manger about this. He looked it up for me. Parts and Labor is $800 to have the reservoir replaced once every 60,000 miles or 6 years.
I'm hoping the belt replacement will be tossed in for zero additional labor.
Does anyone know why the reservoir needs to be replaced at 60K? What happens to it after 60K miles? It's a little puzzling. A fluid reservoir isn't like an air filter or spark plug that wears with every mile and needs regular replacement.

It has an integrated filter. The only way to change the filter is to change the reservoir. Gah. I guess this philosophy worked for them with the PDK clutch filter (it is integrated in the pan), so they are running with that theme.
Tech send me a picture of what had to be removed to get the PDCC pump out and in doing so scratched a coating off the fluid line that goes into the back of the PDCC pump which also acts at a seal so it needs to be replaced before everything goes back together. It has to come from the mother land.

FWIW the actual part is not super pricey. It seems the labor is the killer piece.
Also I assume the reservoir is plastic and if it's anything like the Audi Coolant reservoirs, the plastic wears out over time with all the heat.

I would bet that it is the same sourced-from-ZF hydraulic (power steering) fluid reservoir (with integrated filter) that Porsche has been using for decades. It doesn't degrade except for the filter.
I'll post up the cost when I get the car back later this week. I've already outlined with a sharpie which kidney I'm going to remove when I go pick it up.
If the factory tool didn't scratch the darn fluid line going to the back of the PDCC pump the car would have been back together today.
Even with this delay I've given them a list of stuff to do to keep them busy until the part comes in. Tank pads replaced, some bolt in the dash replaced (hopefully will solve the dam "chirp" I get every once in a while from behind the instrument cluster), brake fluid flush, rear interior side panel reattachment, computer updates........ but the biggy was the belt and PDCC bottle replacement which I was not going to tackle myself.
I'm cruising in a new Q7 which is making me sea sick from the sway in the suspension that feels unnatural.
Here's a picture of the coating scratched off the PDCC fluid line.

The RWS seems more attractive and is a plus for handling, but I have no idea of the complexity, weight added or cost to maintain. Anybody have any light to share or offer on ownership costs of RWS?
If $800 every 60k miles is all PDCC costs extra to own, that's not that bad and would not scare me off.
My C2S garage queen is near 2 years old and has 5400 miles on it, so that PDCC cost would certainly not scare me.

I saw a video on the 911R which has RWS. The Porsche engineer was questioned about the weight of RWS and his response was that it only added 6 pounds to the car.
I asked my service manager about additional maintenance for RWS and he said there was none. (other than the discussed replacement of the reservoir) No harder to align the rear wheels than without out it.
However, he did agree that every time you add a system to a vehicle or make it more complex there is also an added risk that the system or a portion of it might fail at some point.
Well anything is possible with enough cash, but my guess is that it would be more cost and time effective to trade in your 991.1 for a 991.2 with RWS.
You would probably need new rear hub carriers in the rear, the complete hydraulic system and some type of Computer upgrade to integrate to the ECU and Suspension logic and PSM to make it work as designed, as well as the rear actuators.
I can't imagine this upgrade being possible without at least 20-30,000 dollars and a ridiculously talented Porsche Tech.
