They have a long history of tightening the requirements to receive the grant and other incentives, so I would not be surprised. We were early adopters of the Toyota Prius and got a grant of several thousand pounds plus benefits like low BIK, low road tax and Congestion Charge exemption. Our Prius produced close to 100gm CO2/km and is no longer eligible for any of those benefits. As the Outlander becomes popular, they will almost certainly drop the CO2 limit, or require longer EV range.
