I did give myself that escape hatch of "wherever possible" for this stuff.  I'm given to understand that the work to get Perl to support multiple implementations of Unicode in the same runtime is probably further toward the "not" end of the "wherever possible" spectrum and that this would likely be a case where we'd be best served by relying on the Unicode Consortium's own backward-compatibility promises.  I don't know that it's worth spending a lot of time exploring the nuances of this one until we have an upgraded version of Unicode that breaks something new and exciting that we can't possibly live without.
