Unless printable representation of bytes objects appears as part of the language specification for Python 3, it's an implementation detail, thus, it is a candidate for change, especially if the BDFL wills it so.

So this is all about the output of repr(), right? The question then is: How important is backward compatibility with repr? Will there be code breakage?

It’s likely to break doctests at least.
