I think that successfull completion of this project should be a clear
and justified answer to the question "Is this idea is good enough to
work on merging it into the master?", not the production-ready patches
themselves. Nevertheless, of course project success criterion must be
reasonably formalized -- e.g. implement nodes X with features Y, etc.
