My rewritten version of PEP 414 is now up (http://www.python.org/dev/peps/pep-0414/). It describes in detail a lot more of the historical background that was taken as read when Guido accepted the PEP.

""" Just as support for string exceptions was eliminated from Python 2 using the normal deprecation process, support for redundant string prefix characters (specifically, B, R, u, U) may be eventually eliminated from Python 3, regardless of the current acceptance of this PEP. """

We might need to clarify the feature's longevity. I take the above to mean that use of u'' and/or U'' won't emit a deprecation warning in 3.3. But that doesn't necessarily mean its usage won't emit a deprecation warning in 3.4 or 3.5 or 3.6, or whenever it "feels right"? Does that sound about right?
