Auto-Cancel Macros on Move: Could It Be Done?

Just a thought...
As of the moment, I have only known that abilities (individually) cancel themselves when you move your character. Should there not be an option or macro command that apply the same functionality to macro scripts? Having an ON/OFF option, in the configuration menu or such, and a matching toggle command for such a procedure would be nice, but if that would cause some sort of correlation toward ethical macro construction, then it doesn't have to be togglable; it could be a command that applies similar to /macrolock, and only affect any code after it.
