Here are the requirements:
- The computer must have at least 1 Gb of dedicated VRAM (2 Gb recommended) and it must support OpenGL version 4.0 and greater; AND
- The computer must have a native Retina display (e.g., MacBook Pro, iMac 4K, iMac 5K, etc.) For computers like a Mac Pro or Mac Mini, they have to be connected to a HiDPI (Retina) monitor
You probably don't have a native Retina display on your Mac.
Why would a Retina display be required for acceleration? Sounds like since it's not one of the officially supported video cards by Apple that Adobe have dropped the ball in regard to InDesign. Photoshop and Illustrator have not though, so all hope is not lost.
I have the same problem, but my video card has native drivers in the OS.
Although it looks like they do test different cards for Photoshop though.

I can't answer why the engineers made that decision. Perhaps, they decided to limit it at first, and expand the capabilities later on. It's unlikely that they will reply to this and tell you why that decision was made.
All I can point you to it to make a feature request here:
