I agree that get_categories() is designed mearly for categories, However,  
As Malaiac has pointed out, creating a new  function would involve  
duplicating a lot of the functions which rely on it.
I do not see any harm in moving 'taxonomy' into the args list for the  
default, And doing so should mean it'll filter down from the functions  
which rely upon the get_categories() function
