Once upon a time it was possible to change the default tags of elements. By the best of my memory, I do not know the reason why this abiloty was changed, but not changing default tags keeps leading into restrictions when you want to work with "default" tags alongside non default tags.
An example are hovers and vertical boosters: Both are by default targetted by the default groundaltitude. There are situations where one simply does not want the default script to apply to all hovers/vertical boosters and the only current alternative is to develop a whole new groundaltitude function, instead of selectively employing the existing one.
