Bollocks [TM].

Making one command require another one to be used first is a bad idea
unless it can be justified in contextual terms. Requiring GROUP before NEXT
makes sense. Requring LIST OVERVIEW.FMT before HDR doesn't. What are you
going to do if the client doesn't bother ? Reject it for being awkward ?
