Right, but if you start using those new API in standard lib
functions, programmers no longer have that choice.
In real life applications, you do run into these problems quite
often, so instead of coding against an ideal world, we have to be
aware of the problems and make it possible for the standard lib modules
to deal with them.

Sure, but forcing UnicodeDecodeErrors upon Python3 programmers is
not a good idea. Please keep that in mind.
