Indeed, it applies to the project as a whole.  I have however, gotten
some private feedback that to me says that there are companies out there
afraid that because we retain our "+" we're going to switch to GPLv3 any
minute, rather than keeping our options open, should some future GPL
provide a compromise both developers, companies and regular consumers
can live with.
