In theory this should show a warning, but for some reason it doesn't.
Reading the messages on http://bugs.python.org/issue1247765 it seems
that there wasn't a clear consensus about the deprecation schedule, so
that might be the reason.
If the warning is missing just because no one remembered to add it, I
guess it can still be fixed on 2.7, but for 2.6 is too late now.

FWIW you get a warning if you use the -3 flag:
  $ python -Wd -3 -c "import new"
  -c:1: DeprecationWarning: The 'new' module has been removed in
Python 3.0; use the 'types' module instead.
