+ some styles around (or even own extension to provide custom directives)

The problems are:
- Big merges: we'll have a lot of "unstable" or not "tested

- Psyhology: marking something as experimental raises interest from
hackers and advanced users, regular users will never use these things.
Unstable badge is not so attractive for hackers, but still regular
users will try to avoid such API. As the result, API and features will
not receive good feedback from wide people and this will create
deadloop: need more feedback to mark feature as stable, need stable
badge to use feature intensively and give a lot of feedback. Time is a
good tester, but it doesn't writes bug reports. Stable looks good, but
