I don't mind such a decision in principle, but also in principle, I'd
prefer if there was a pre-set policy to decide this question, documented
in PEP 11.

Here a piece of OSX release history:
- 10.5:       October 2007
  * 10.5.8:   August 2009
- 10.6:       August 2009
  * 10.6.8:   July 2011
- 10.7:       July 2011
  * 10.7.5:   July 2012
- 10.8:       July 2012

So possible policy that would now exclude 10.6 for binary installers
would be:

- only the two latest feature releases are supported
- only feature releases younger than 3 years are supported

Note that a separate policy should be added to decide whether support
for older versions is actively removed from source code (or equally
bug fixes for old versions are not accepted anymore).
