Apple would be the only ones that can answer this completely so take what's below with a grain of salt. @litherum feel free to correct me if I'm saying something wrong.

AFAIK the "WebGPU" exposed by Safari was their previous "WebMetal" implementation and just one of the very initial proposals for this standard. WebGPU is currently being implemented in WebKit (which powers Safari) with some of the code being here. There's some movement but it looks like it is implementing only a fraction of the API surface so it will take at least some time before it can be shipped on iOS.

It doesn't look like it's making any significant progress whatsoever. Why remove the old (partially working) implementation, when the replacement isn't ready whatsoever, nor the development of it prioritized?

To me, it seems like Apple is trying to backpedal on the whole WebGPU thing.

And it would also be nice if the Wiki in this repo could be updated to reflect the new lack of availability in Safari TP, since saying it's available when it isn't is misleading.
