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?

To be explicit, when the system loada them.

I don't think that's a good way of promoting their use :)

And importing something from __preview__or __experimental__or whatever won't? This thread did include the suggestion that they go into their final location instead of a magic module.

(something we do want to do even though we also want to convey the idea that they're not yet "stable" or "fully approved")

Doing it with a message pointing at the page describing the status makes sure users read the docs before using them. That solves the problem of using them without realizing it.
