Perhaps a better way to handle this would be to create an official API 
to handle this problem, then distribute it as an external Python file 
you can include, which will have some forward-compatibility code put 
into it when newer versions of Twisted come out.

I don't like the "let's never change anything because someone might be 
using it somewhere" approach that we've been taking.  When we're making 
minor changes it's good but over time (especially given the sprawling 
nature of Twisted and the lack of any documentation on the state of its 
entirety) means tha we leave chunks of deprecated or semi-deprecated 
APIs around forever.
