'Not respecting pick order' as a report option.

How is 'not respecting pick order' not a report option yet? I mean 'pick order' is something that is so ingrained into the game and the psyche of the player base, and is something that is generally accepted as the fairest way to choose who goes where, that it seems odd that there isn't a report option for people who violate this. Am I missing something as to why it isn't?
