OpenGL still works on the M1 (Apple designed their own GL-over-Metal driver), albeit with the OpenGL version limitations from modern macOS in general. Vulkan works over MoltenVK.

Other than old games, I'm not sure why 64-bit only is an issue.

I've not hit any Docker-on-macOS issues with what I've used it for, at least.

Is MoltenVK usable right now? I was under the impression that it's a loooooooong ways behind DXVK in it's current state.

I've seen plenty of projects that use MoltenVK as a drop-in backend for macOS. It seems complete enough for general use, but I haven't used it directly so I'm not sure what's missing.
