rollback

I understand the restrictions of rollback and the care required in its use (for example, http://www.selenic.com/mercurial/hg.1.html#rollback), but I just wondered why there is only 1 level of rollback.

My guess it's a design decision and that the hassle of storing multiple previous transactional states to handle multiple levels of rollback is more trouble than its worth.
