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.

No, the main issue is a fundamentally different rendering pipeline (tile based deferred rendering) that makes "Vulkan support" a conceptually difficult square peg in a round hole problem, since everything is made for immediate rendering, like all the other mainstream GPUs use.

Loads of GPUs with Vulkan support use TBDR. The Adreno GPU in the Steam Frame's SnapDragon SoC, for one.

There is also a Vulkan driver for the M1/M2 GPU already, used in Asahi Linux. There's nothing special about Apple's GPU that makes writing a Vulkan driver for it especially hard. Apple chooses to provide a Metal driver only for its own reasons, but they're not really technical.
