Subject: [PATCH] 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.
