Mr Griffith would certainly choke on his noble words should his team ever lose a vital match or a Premiership because a referee makes a critical blunder that might have been fixed by the TMO. He will in all likelihood be among the first to criticise that referee for his mistake!
I fully agree that Pandora's box, once opened, will remain so.
Perhaps I am old-school - my father certainly is - but I do not believe that in the history of rugby there has been a vital match lost "because a referee makes a critical blunder". And yes, I am fully aware of

Games of rugby are won, in general, by playing the game better than the opponents. Ian_Cook, I believe that this is how the team you support wins matches, again, in general. Sometimes the teams are roughly equally good on the day. They have similar resources (financial and otherwise, from the highest level to the very lowest), and the game is tight. In such games, a single decision by the referee may determine the final result, and as a consequence also promotion/relegation issues with all the implied financial concerns of sponsorship.
I am a referee, and also a coach. As a referee, I have come across as coaches that get on my wrong side. I have come across more coaches by a factor of ten who are proud when their team wins, but respectful of my decisions both during and after the game. I don't have a TMO, obviously.
Ian_Cook, what drives you to sat that a coach would CERTAINLY choke on his "noble" words? I don't know Mr Griffith from your mother, but would you post about your mother/sister/daughter that way if she suggested that players could live without TMO decisions?
