There is no way this is a replacement for the RealSense depth cameras. These are USB, bus powered, factory calibrated, cameras doing the block matching in an ASIC. Often with an IR projector to help the matching. This like saying, oh well, I can’t find a GPU, so I’ll just compile Mesa for the CPU and my product will be fine.

Put an NVIDIA Jetson Nano in between and you also have hardware matching.
IR projector is $19: https://www2.mouser.com/ProductDetail/ams/AQAA-20?qs=DRkmTr7...
This seems a little bit like claiming that while you can't deliver an aircraft carrier right now, you do have several canoes available and since they both float it's basically the same thing.

Yes and no. Of course, a homemade module like this will be way less polished than a RealSense camera. But on the other hand, it'll be more flexible and possibly tailored to your problem. So a homemade module might actually have better performance.
That one only has 4700 dots, which severely limits the potential applications. The one in the iPhone face scanner has 30,000 dots. (Last time I looked, it was very hard to source IR projectors that you could use to make a reasonably accurate depth camera.)

It has about 5500 dots so it should be similar to the projector inside a RealSense D435.
