I would very much like to have the option for XKCD style passwords as an option
in IPA:

With traditional style passwords becoming less and less secure, doing this
would be quite helpful.

I know it can be simulated by just doing it, but there's no way to do that and
have traditional passwords at the same time (while transitioning.)  An actual
password policy that I could apply to just certain groups would be the right
way of going about it.
