there was a qt package and a qt4 during a certain amount of time before the 
switch to qt3/qt

yes and no. because the number will grow very slowly and there is no such big

why not wait until python 3.1 ?

i really fear that a great number of software will break because they will try 
to use /usr/bin/python and except a python 2 to be there. 
What about the package in unsupported that will not be upgraded asap as the 
others in extra or core or community.
