Does it - I can't find any evidence for that.
It seems self-evident to me. What do you think is it prime purpose?

Debugging and testing. At least that is as I understand it much of where
it came from.

Good call. Though I suppose, since it's used 24x7 to aid security on countless production servers, that security dwarfs testing. Still, debugging, yes that's valid.

I don't suppose it makes and difference; whatever the purpose, a chroot that doesn't change the root is buggy.
