minor nitpick: did care when Google Stadia was in the list. But it did not worked out and everyone took a big L on that and now Vulkan support has been mostly purged already.

The reason why Stadia is no more, is exactly because they don't care.

Google was starting to offer a DirectX porting kit on the same year they decided to ramp down Stadia, there is even a GDC talk on it.

My opinion on the facts I saw don't agree with your interpretation. No one here on HN cares about it =) so I just drop it.

My hot take is that when AAA games will be shipped on mac os they will not use porting kit in runtime and just call Metal. Imho API court battles are fun to watch from afar.
