Hi Jim,

Thanks for your testing. Yes, I plan to add the notice to other sub-commands as needed. I only updated REPLICA IDENTITY first to call for feedback. As you see, David has suggested the great wording for the notice message. Once the change on REPLICA IDENTITY is reviewed, it’s easy to extend to other sub-commands.

Best regards,
