The eCVT has RPM limits that would be easily exceeded if it didn't have tight controls on it. The reason you can't drive faster than 42 miles per hour without the ICE coming on is due to the MG1 will be spinning at its max of about 6500 RPM at that speed. If you could shut off the VDIM, I suspect the PSD would be easily damaged.

The up-side is I've been really impressed with the VDIM in extremely icy conditions. Not that I enjoy going out on such days, but if the VDIM can't find traction, you won't either. This last winter, the vast majority of vehicles in the ditch were big trucks where there's a false sense of control. If you're frustrated going 5mph in your TCH, go home, get a good book, and wait for the ice to melt.
