You are not the first person to complain about this and you won't be the last. Nobody has heard anything official regarding parts availability. The original recall document said early 23, last fall we heard June of 23, a month or 2 ago we heard third quarter of 23 and a separate account of october, which aligns with the 3rd quarter estimate. All of those are unofficial though, so who knows.
Think about it this way. The CP4 has been a known issue on many different engines for over a decade. Of all the engines that have used it, The EcoD seems to have fewer issues than any of the other platforms, and yet RAM is the only manufacturer doing a recall. You should be happy they are at least doing something for you, and not hanging you out to dry like GM and VW do to their customers. And I would think if you're concerned about getting a "soundly engineered solution" you would want them to take a little extra time and do it right. Of course if your pump grenaded and your truck is sitting at a dealer waiting for parts, the story is a little different.
And as for your comment about the cummins, it is not perfect (no vehicle is) and it is subject to recalls too. 2019 and 2020 model year cummins engines also used the CP4 and are also going through a recall, so you'd be in basically the same boat. There is also a transmission recall for some of them (I forget the years). And parts availability is questionable for a lot of different recalls from many different manufacturers right now, not just the EcoD.
Is it right? No. Do we have a choice? Not really. So unless your truck is sitting dead at the dealer waiting for parts that aren't available, there's no point in complaining about it. Just drive your truck, enjoy it, and sit back and wait for your brand new free pump.
