Well no, I didn't say that. There were reasons for the move to Proto in
all cases, mostly DSEL interoperability. Spirit.Qi and Spirit.Karma
share terminals and host Phoenix expressions as semantic actions. Moving
them all to Proto made sense. And the Spirit rewrite wasn't motivated by
a move to Proto, either; that change went in at a later date.

I haven't made (nor could I make) such a proclamation. Boost doesn't
work that way.

The Phoenix rewrite is still a work in progress.

You don't see me volunteering. ;-)
