They use standard MM+ code that is extensively tested so no significant support overhead. The tweak to use them on the CMM2 is just to integrate the mouse rather than touch. There are no further new commands envisaged so this is just a case of adding existing code and using the free slots that were there.
My view FWIW is that now the CMM2 code is reasonably mature and the mouse integration works well the GUI commands add useful functionality for lots of potential "non-embedded" applications and so the previous arguments against no longer carry as much weight. With OPTION MAXCTRLS set to 0 the new functionality imposes no overhead on the firmware so can be ignored completely for anyone who doesn't need it.
