If there were TCO advantages with this setup, CUDA would not be a blocker.

CUDA's just one example; there's a lot of hardware support on the BSDs that Apple doesn't want to inherit.

Why maint other and have baggage ?

		Because Apple already does...? There's still PowerPC and MIPS code that runs in macOS. Asking for CUDA compatibility is not somehow too hard for the trillion-dollar megacorp to handle.
