Would love to see it on MacOS X -- Steam works great on my Mac Mini for the games it supports, would be great to see everything run on it.

Main issue is the lack of Vulkan support on macOS. Currently, solutions like MoltenVK have to be developed to add Vulkan support, which isn't as clean as just supporting it.
For some reason the prospect using Wine, Rosetta 2, and DXVK with MoltenVK on top just to run some games doesn't inspire a lot of confidence that this whole thing will be performant and/or stable.
