That's true if the feature has some functional effect on users. But at
first sight, VMI is really just an optimisation, and a non-VMI-equipped
kernel would be completely functionally equivalent, right?
On the other hand, there could well be a performance regression which
could affect users. However they're taking the explicit step of
withdrawing support for VMI, so I guess they can just take that in their
stride.
