 > I'm not after parent terms at all.

 I understand where you are coming from and you may not be after the parent
 terms, but others might. If we're going to add another parameter to
 `get_terms()`, shouldn't it at least be useful in more situations? Not
 just for one limited scenario where you add `false` to get the bottom
 terms. What is the utility here? I'm not trying to be argumentative for
 the sake of it, I'm just having a hard time seeing the value in this
 change as it's current presented. Could you please give me an example of
 how other developers could leverage this enhancement so I understand your
 point of view better?

 > I can see the use of a parameter like this, but it'd be a totally
 separate enhancement from 'childless'.
 In the description of this ticket it describes adding a parameter that
 does the opposite of `parent`, so shouldn't it live up to that a little
 bit more? As well, if we went that route and added a separate parameter
 (new ticket) wouldn't we be breaking up what is essentially one function
 set, as `parent` has already proven? If this stays named `childless` and
 we decide to proceed at some point in the future with that second
 enhancement merging the two would be confusing at best.
