Then again: how many uses of mapcar* have you encountered?
If you object to `union' because it's not used often, I'd expect you to
reject the vararg version of mapcar.
The issues are not similar. One is adding a new function.
The other is a simple, natural extension in an existing function.
The former costs more, in complexity.
