This reports the outcome of the most recent action triggered against a named feature set. Because a feature-set action can cascade across multiple bundled individual features, a failure result here might stem from just one of those underlying features being unable to comply, for example still in use, so this result is where an admin starts before digging into the individual feature-level failure details. A failed attempt to disable the fex feature set might reflect that one specific attached FEX module refused to disable because it still has active host connections, blocking the broader feature-set-level action.
