Back-story: I don't remember the details of your code (will have to look
again), but I do remember that Joel d.G. made a design decision that
Phoenix3 extensibility shouldn't require deep Proto hacking, or any
Proto at all, IIRC, at least for simple things. That's how we ended up
settling on the current design that mostly shields users from the Proto
guts. But no worries, it's still there under the covers.
