Excuse me, but I can't see a scheme that encodes bytes as Unicodes but
only sometimes as a "clean separation". It's a dirty hack that makes
life a lot easier for Windows programmers and a little easier for many
Unix programmers. Practicality beats purity, true, but at the cost of
the purity.
The problem you don't address, which is still the reality for most
programmers (especially Mac OS X where filesystem encoding is UTF 8), is
that programmers *are* going to treat filenames as strings.
The proposed PEP allows that to work for them - whatever platform their
program runs on.

So what you'll get here, AFAICS, is a new situation where many
Windows-centric programmers will produce code that's incapable of
dealing with non-Unicode input because they don't have to care about
the distinction between Unicode and bytes.
That's an improvement, but we can do still better and not at huge
expense to programmers.
