It does not mean that. I just restricted to three examples. There is no problem to rewrite all options that xkeyboard-config offers to switch groups to take advantage of the patch.

In this case, one needs to remap the shift key. For the left shift key:

    key <LFSH> {
        repeat= No,
        type[Group1]="PC_CONTROL_LEVEL2",
        symbols[Group1]= [ Shift_L, Shift_L ],
 actions[Group1]= [ SetMods(modifiers=Shift),
                    Private(type=3,data[0]=1,data[1]=1,data[2]=1,data[3]=0,data[4]=0,data[5]=0,data[6]=1) ]
    };

For the right shift key it works similarly. If combined with the third example above, it will make the order of Shift and Control irrelevant.
