But you'd still have to validate it, right? You wouldn't want to go on using what you thought was wrapped UTF-8 if it wasn't actually valid UTF-8 (or you'd be worse off than in Python 2). So you're really just worried about space consumption. I'd like to see a lot of hard memory profiling data before I got overly worried about that.

I do know for a fact that using a UCS2-compiled Python instead of the system's UCS4-compiled Python leads to measurable, noticable drop in memory consumption of long-running webserver processes using Unicode (Zope, repoze.bfg, etc). We routinely build Python from source for deployments precisely because of this fact (in part -- the absurd choices made by packagers to exclude crucial bits on various pltaforms is the other part).
