Backport #975 from trunk:

  Warn the user if he/she recalls a sample with EXPERIMENTAL features.
  Also, print the EXPERIMENTAL status when listing the samples.

NB: even it is not purely a fix backport, it is still very important that the user gets warned about the EXPERIMENTAL status of the samples.
