That's one of the best summaries of the situation I've ever seen :)

Most languages (including Python 2) throw up their hands and say this is
the developer's problem to deal with. Python 3 says it's *our* problem to
deal with on behalf of our developers. The "surrogateescape" error handler
allows recalcitrant bytes to be dealt with relatively gracefully in most
situations. We don't quite cover *everything* yet (hence the complaints
from some of the folks that are experts at dealing with Python 2 Unicode
handling on POSIX systems), but the remaining problems are a lot more
tractable than the "teach every native English speaker everywhere how to
handle Unicode properly" problem.
