It seems that I need to update the proposal (http://lists.w3.org/Archives/Public/w3c-wai-ua/2012AprJun/0028.html):

UNCHANGED:
3.2.1 Form Submission: The user can specify whether or not recognized form submissions must be confirmed. (Level AA)## DONE 15 March 2012 
3.2.2 Back Button: The user can return to a previous state or view using a navigational back button or its equivalent. (Level AA) ## DONE 15 March 2012

PROPOSED:
3.2.X Undo: The user can sequentially reverse a series of *reversible user actions*. (Level A)

New glossary term: reversible user actions:
Actions that the user agent recognizes can be immediately and completely reversed because either:
(a) the actions occurred exclusively within the user agent user interface, without any server-side or client-side processing; or
(b) the web content provides a recognized programmatic method for passing an "undo" command.
Note: It is acceptable to collect a series of text entry actions (e.g., typed words, a series of backspaces) into a single reversible user action.

3.2.Y Settings Change Confirmation: If the user agent provides mechanisms for changing its user interface settings, it either allows the user to reverse the setting changes, or the user can require user confirmation to proceed. (Level A)
