> With "t", it takes/gives Unicode objects, but with "b" it uses bytes. Sure, in Python 3, but not in Python 2, or C. Anyway, moral correctness is beside the point. People in point of fact don't write encoding='utf-8' when they should, because it's so much to type. If you had to write binary=True to enable binary mode, fewer people would have bothered to use it in the Python 2 era, and there would have been more portability (and Python 3 transition) problems. There shouldn't have been, but there would have been. Everything about the mode parameter is a sop to convenience. Really you should write open(mode=io.APPEND) or something.
