Put another way... If we have a jail that lives in /foo/bar, and we have ways to symboliclly link outside /foo/bar, that's a big problem. Also, you really don't want too many devices in a jail's /dev tree. You really wouldn't want devfs for jail unless you could limit it severely. And that's going to be hard to write, I think.
