What's the point in developing code you won't use? __preview__ features
don't have a Roadmap, so you may wait forever to release you package into
production. With indefinite release cycle __preview__ will become useless
for the most people, who will quickly lose enthusiasm to use __preview__
and continuously update their code for API breaks.
