I think I've found the Debian discussion (October 2012): http://comments.gmane.org/gmane.linux.debian.devel.python/8188 Lack of PYTHONWARNINGS was brought up late in the discussion thread but I think the understanding that when a particular user sets an environment variable they want it to apply to all scripts they run was kind of lost in the followups (It wasn't directly addressed or mentioned again.) -Toshio On Thu, Mar 19, 2015 at 12:27 PM, Barry Warsaw <barry@python.org> wrote:

I could see that as a difference. However, the environment variables give users the ability to change things globally whereas overriding the shebang line is case-by-case so it's not a complete replacement of the functionality.
You make some good points. I guess it's a trade-off between flexibility and a known secure execution environment. I'm not sure there's a right answer; different admins might have valid different opinions.
