I offered examples, you were too lazy to read the changelogs, your sweeping
declaration does not seem justified.

>From What's New in Python 2.6:

contextlib: attached to a language feature.
multiprocessing: backported
new string formatting: though a method, it'd be easy to produce in a module
form.  I'm not aware of a backport.
abstract base classes: I don't think this can be backported wouldn't all
kinds of contortions
ast: associated with the implementation/language
json: backported (implicitly, as it is simplejson)
plistlib: I'm guessing this was added to support packaging.  It exists
separately.

What's New in Python 2.7:
argparse: implicitly backported
changes to logging: not sure what will happen with this; the module has been
backported in the past
memoryview: not aware of it being backported
importlib: technically including it in 2.7 is a backport, but otherwise no
ttk: appears to be backported (http://pypi.python.org/pypi/pyttk/)
unittest: backported
ElementTree: backported

Digging deeper into 2.5:
functools: apparently backported at one time, now defunct
ctypes: the backport appears to be dead
sqlite3: actively developed (different name?)
wsgiref: backported
hashlib: backported

Every release there's some additions to collections, which have not been
backported.

So in summary, of 17 additions which seemed "backportable" to me (not
counting 3 modules that seemed tied to language features):
* 4 were not backported
* 3 have defunct or ambiguous backports
* 10 were backported
