> No Metal support is IMO no problem. I and most of the rest of the games industry couldn’t care less about MSL. Nobody uses it. I’ve seen numbers from Apple that say upwards of 80% of developers they asked target Metal via SPIR-V Cross and HLSL from DXC.

That is a real, real shame with respect to performance. A number of algorithms one can do with MSL (or really because of tile based rendering) so much faster (nearly no main memory bandwidth consumption). Atleast there is GL_EXT_shader_pixel_local_storage for GL. For Vulkan it appears that there is VK_EXT_shader_tile_image, but I do how widespread it is on Android.

There are other nice features that are Metal-ish only as well (tile shaders are a big deal) but typically the memoryless textures tops my list.
