The difficulty is that if existing libraries use a particular class and inherit from it, changing the class to be new-style can have effects from changing how their descriptors work to causing an exception when their module is imported. We have a compatibility policy, intended to prevent people's applications from breaking when they upgrade Twisted: http://twistedmatrix.com/trac/wiki/CompatibilityPolicy If old-style classes can be evolved into new-style classes while somehow following this policy, that would be great. The problem is that providing compatibility at this level is time-consuming and difficult. One problem in particular is that we don't want to litter the codebase with lots of "Foo" and "NewFoo" or "Foo2" sitting right next to it, so we would have to think of new names for everything. If you have a particular interest in the new-style vs. old-style problem, please feel free to submit patches! This is one of those areas where we need a continuous stream of small improvements from the community, because it's just too much drudgework for the core team to take care of in our spare time.
