I was going to suggest that this might be a documentation issue, but the existing documentation already looks sufficient to me:

> A user may need to set the limit higher when they have a program that
> requires deep recursion and a platform that supports a higher limit.
> This should be done with care, because a too-high limit can lead to a
> crash.
