If you take this text seriously then companies like Redhat advertise 
their enterprise distributions with alpha-test quality software...

Facts are:
- as long as we allow hardware drivers to depend on EXPERIMENTAL we
  force many users to enable EXPERIMENTAL
- the EXPERIMENTAL dependencies in many areas of the kernel are so
  out of sync with the actual code quality that the presence or absence
  of such a dependency isn't a clear indication of the current status
