That said, I do agree that I wish it could be used as a monitor.. even to power a laptop would be great. There used to be a way to do it but it died once we hit 5k.
- Connect one to either left port, and one to either right port, of the iMac Pro.

Now, personally, I want my computers either portable, or loosely coupled to the monitors. But the iMac Pro is quite a capable machine.
The best Apple solution at the moment is to use MBPs in this way, unless you want the ultra expensive Mac Pro.
