I admit, this concerns exclusively code aesthetics but it might slightly improve code maintainability and oversight.

Another point, which works in favour of the WrapperClass/<action> approach, is that with that approach you can get away with just one mex function. You can then call it with a parameter, e.g. a string, to denote which class function you want to call. That's the way I'm currently doing things, but it is entirely aesthetic, you're right.
