Agreed. There were other, similar opinions in that thread: http://lists.debian.org/debian-python/2011/07/msg00035.html
Once the PEP is approved and upstream Python finds a way to implement it (it would be a new feature and features aren't added to point releases and there will be no pyhton2.8 - the implementation path is murky at best) then Debian should (even though I don't like the idea) follow upstream on this. In the meantime, this should be dropped.
