I'll admit my first thought on reading the initial discussions about adding bytes % formatting was "Oh, if I want to display custom objects in a byte stream, just add a __bytes__ method."

I don't believe there is any verbiage in the PEP (that might get transferred to the documentation) that explains why that would be a bad idea. Should there be? Whether or not %a is implemented sooner or later?
