How. About doing them the way we do depreciated modules, and have them spit warnings to stderr? Maybe add a flag and environment variable to disable that.

You're proposing that new experimental modules spit warnings when you use them? I don't think that's a good way of promoting their use :) (something we do want to do even though we also want to convey the idea that they're not yet "stable" or "fully approved")
