In fact, no, the old binding was not working for anything but NSR. It pretended to support SEI, REI and SR, but because these had never been implemented, the binding was not sufficient to over them. To support SEI or REI, we need to point to a different msi-parent than the one used for NSR, which wasn't possible with the previous binding. So there is no regression of functionality by this binding change, quite the contrary, as it really allows to add SEI support, which was not possible before. You can consider that the previous binding was buggy and dysfunctional.
