Perhaps a compromise between these two approaches would be more acceptable and compatible with existing programs. What if (ALL NON-COMPLEX DIATIC OPERATORS) saved both X and Y, by calling the setlastXY() function instead of the setlastX() function then one could recall either X or XY, by choosing RCL L or CPX RCL L. The CPX RCL already handles the dual stack lift and recall of both X and Y.

I know this wouldn't take care of Z and T for Complex diatic operators, but it wouldn't be difficult to implement, wouldn't take any additional storage, and would break very few existing programs.

Any thoughts?
