I think the general convention of using a prefix to indicate some class
of flavors is well established and understood, so in general I don't
like the idea of making our defaults not have a prefix.

I'm also not seeing a compelling reason to change to a different prefix.
 It's just the defaults, and I imagine most people configure their own
flavors for a production deployment anyway.
