That's not entirely true. Whiskey being depreciated to support Codeweavers was a headline story this week - something that outright would not need to exist if Apple users could run upstream DXVK instead of GPTk.

That doesn't work either! Paying Eidos and Capcom and Hello Games did not start an avalanche of ports. Apple could license DirectX from Microsoft, but they could also just support Vulkan 1.2 and get perfect DX12 coverage through translation.
The bigger point is that the Metal-only route isn't working. We can argue over the merits of Vulkan until the cows come home, but the simple issue is that Metal doesn't get ports. Native APIs on Apple platforms just get ignored.

For macOS, no. For iOS, yes, and that's where Apple makes almost all their revenue. Apple wants your primary target to be iOS. If you decide to do a macOS port, that's nice but not essential. Of course this doesn't work for AAA games, but that's a sacrifice they're happy to make.
