Can this be handled in a more generic way, the fixes to experimental features? If you pass that through AI, it should be clear from the context (changelog or code). The config option has been added also for that purpose, it does not make sense to backport that and assign CVE's eventually. Experimental features are only for those following the most recent release. Thanks.
