I believe it does. Creating a new Error-instance to learn what the current stack is a bit hacky, but it can be useful, even when there is no error. The code can reflect on who is calling it.

Sometimes a function or method is called very many times so trying to log them all is useless. But at the same time it can be the case that there are multiple callers of the said function. Then looking at a stack we can log just the case of some specific call-chain calling that function.
