There's nothing preventing anyone from using twisted.python.log like this
right now.  The implementation could be adjusted to provide better
performance for this case but that's hardly a blocking issue preventing
anyone from doing creative things with logging.

As you mentioned, Allen has effectively used it this way.

I think the real reason we don't see this usage more is that it is pretty
advanced and most people *do* just want debug spew.  You have to get quite
a ways into the development of a library or application before you start
worrying about the things this functionality can help you with.

Oh, and I still think the format argument is redundant and stupid :)
