I guess I agree that ibuffer should be part of the standard distribution. Less sure about undo-tree, but could be an option if the authors released it under appropriate licenses (I understand that contributing code to Emacs is somewhat cumbersome; although if I were smart enough to do so, I would jump through the hoops in a heartbeart).
