Are you talking about general porting, or about Twisted?

It is a common misconception that "drop everything prior to 2.6" was
a recommended step 0 for porting to Python 3. That was never
recommended.

Instead, what *was* recommended is "port to Python 2.6", which for many
projects already supporting, say, 2.5, was a no-op, so people read more
into that than was actually necessary. With the project ported to 2.6,
you could then make use of the 3k warnings to learn what issues you
would face when porting to 3k.
