'cxl list' hides zero-sized decoders unless --idle is given, assuming they are unconfigured idle slots. That assumption does not hold for locked HDM decoders, which may legitimately report size 0 while being committed by firmware. Do not suppress locked zero-sized decoders from the default listing. Combined with the "locked" field in the decoder JSON, they are visible and distinguishable from idle, unlocked slots that remain hidden without --idle.
