I wasn't referring to Guido specifically, just general code smell complaints about boolean parameters.

Not per se.  But I ran into him when he was leaving PyCon 2012 for good (second night of the sprints iirc), and he steered me to the original python-ideas thread and asked me to follow up on it / work with the poster.  (Probably because of my doing the nanosecond-precision os.stat / utime work.)  If there's genuine opposition to the patch being generated here I'll ping him.

Oh, btw storchaka, in the email thread you asked

No--it'll just be part of a release, and you'll check which version of Python 3 you have before using it.

    if sys.version_info.major >= 3 or sys.version_info.minor >= 3:
       # use extra flags
