python-cjson is on Debian but not on Ubuntu

[Shriramana Sharma]

Dear Python developers,

python-cjson is available on Debian Lenny/Sid but still not there in the 
Ubuntu repos.

Please see:

http://packages.debian.org/search?suite=all&section=all&arch=any&searchon=names&keywords=cjson
http://packages.ubuntu.com/cgi-bin/search_packages.pl?keywords=cjson&searchon=names&subword=1&version=all&release=all

When other json modules for python are available in Ubuntu:

http://packages.ubuntu.com/cgi-bin/search_packages.pl?keywords=json&searchon=names&subword=1&version=all&release=all

is there any reason that python-cjson is not available? It's a recent 
addition to Debian itself (2007-Aug-14) so it may have been overlooked 
but it's a must-include, IMHO.
