This. Previous FW versions lacked the ability to compare 2 profiles, determine their differences, and save the results in a cab.
What I believe is that the Profiler was initially aimed at profiling whole rigs (or rigs once-and-for-all, so to speak). Then popular demand made swapping cabs - and the faithfulness while excluding cabs and using a real guitar cab - a higher priority, so they implemented further profiling functions.
