I think it's fine - if it's an optional thing. I could see it being implemented more as an extension of macros rather than a game-wide change, actually.

One could argue that it dumbs down the game for them - and be correct. Another will argue that it simplifies things in a way that makes it easier for them/others who might have difficulties - and be correct. It just feels like the most positive thing to do would be to add it as a feature for folks who want to/need to use it... And communicate how it's meant to be used properly, while not pushing it as mandatory for everybody.

Easier said than done, of course, but it can be done.
