Distro tools shouldn't be using /usr/bin/env in any case. Does #!/usr/bin/python -E -s work?
No:
Unknown option: - usage: /usr/bin/python [option] ... [-c cmd | -m mod | file | -] [arg] ... Try `python -h' for more information.
-Es together work. I think this is why Unix has the tradition of combining options.
PS. My python doesn't understand -s, so I tested a different options, but the result is the same. There are Unix variants that understand many options (I believe FreeBSD allows them) but most allow no more than one parameter in #!.
