Ok
I was writing this under the assumption that 2 is really entrenched
whereas 3.n is dispensable when 3.n+1 comes out
At least on my debian box 3.2 recently got obsoleted and removed when
3.3 came out.

Obviously my assumption may not always be 'assumable' eg sometime ago
there was someone who wanted to port his old working python app to 3.
2to3 was not working because he was using string exceptions (His code
was 1.something!!)
