> {{BagGroup}} keeps the redundant {{group}} information in its output.
> E.g., see [DATAFU-38]:
> {code}
> (1,{(b,1),(a,2)},{(B,{(B,3)}),(A,{(A,1),(A,2)})})
> (2,{(c,1),(b,2)},{(B,{(B,3),(B,5)}),(A,{(A,1),(A,2)}),(C,{(C,4),(C,6)})})
> {code}
> can be
> {code}
> (1,{(b,1),(a,2)},{(B,{3}),(A,{1,2})})
> (2,{(c,1),(b,2)},{(B,{3,5}),(A,{1,2}),(C,{4,6})})
> {code}
> without loss of information
> Given that the bug [DATAFU-38] rendered this function quite useless and it
> was fixed just last week, I think {{BagGroup}} has not been used before, so
> this backward-incompatible change will not break any existing code.
