No it wasn't. Apple has the resources to support 32bit apps. Wine is looking at adding support in userspace for mac osx. If it can be supported in userspace they could have added a translation layer themselves if they really couldn't stomach keeping it in the kernel.
Apple puts very low-end GPUs in Macs. Most models can't even be upgraded to a GPU that's decent for VR. The base $6000 Mac Pro comes with a $170 GPU! Latest maxed out top-of-the-line MBP has a weaker GPU than the last-gen lower-end GTX 1060.
Perhaps this is anticipating Apple's upcoming move to a potentially new micro architecture that's been reported on -- I suppose if Apple thinks they need a software moat, they'll find a place to trench one up.
