If VMCI was only used on Linux we'd definitely do that; however VMCI
core is shared among several operating systems (much like ACPI is) and
we'd like to limit divergencies between them while conforming to the
kernel coding style as much as possible.

We'll make sure that we will not leak VMCI-specific errors to the
standard kernel APIs.

Thanks,
Dmitry
