If we allowed this, the options to LS transform 2D+1D and 3D could not be used, as I would think in this case you would not want any elevations to be considered/interpolated. You would probably only be using 2x point pairs anyway which also fits in the 2D only LS transformation.
Actually, another option you may consider though is the Modify> Align. This supports snap settings.
