I would like to restart the discussion under a separate subject
because the original thread  went off the specific topic of the six
new methods (2 methods x 3 types) added to builtins shortly before 3.2
beta was released.  The ticket that introduced the change is
currently closed  even though the last message suggests that at
least part of the change needs to be reverted.
Note that reverting part of the patch is not entirely trivial because
new codecs' documentation refers to bytes.[un]transform() both in the
docstrings and the library reference.
I think it will be the best to revert r86934 and resume the discussion
of adding this functionality to 3.3 when we won't be constrained by
the language moratorium. I will write a separate message with my
thoughts about adding bytes codecs in 3.3. Let's keep this thread
focused on what has to be done for 3.2.
