If I cared about Linux VMs, I wouldn't be running macOS as my host.

Maybe you don't, but it's common for macOS users to run Linux VMs to get shit done.

Sure, but for getting shit done, you can always use nested VMs or SSH into a real linux machine if need be. Regardless, the fact that you can run an unspecified amount of Linux VMs yet macOS VMs are limited to 2 is even more egregious. It's far cheaper to get Linux VMs anywhere than macOS VMs.
