I'm pretty sure this is a change of mind, and one I'm quite happy to see. :-)

It is difficult to sanely decide which project plugins for another project ought to be distributed with at this point, and as we move towards more usage of plugins rather than direct imports for integration, this problem is only going to get worse.

I am hella-+10-for-this, as it would make the release process much
much saner, but it's not going to be trivial. Has Divmod yet figured
out how to have multiple top-level "twisted" directories without
running a setup.py? Initially, I tried to hack something together that
munged twisted.__path__ (look that one up, if you don't know about it,
it's way wonky) to include all the subproject twisted directories, but
trial just totally hated that (I remember fighting with
modulename->filename conversion, or vice versa). I can't remember if
that was the only thing that held me back from that solution, but I'm
definitely willing to take another whack at it. Especially now that
trial is massively cleaned up and I live with its maintainer ;)
