The 2015 World Cup will enjoy the biggest stadium and broadcast audience in history and, as much as those running the game don't want to see injustice and controversy, they also don't want those experiencing the game for the first time to be left agitated and bored by endless TMO intrusion.
Perception will be everything and, even if the stopwatch says games aren't blowing out, if ticket holders leave stadiums with a sense they have, the opportunity to convert the casual follower into an avid fan will be lost.
It's a scenario being faced by other sports, with NRL games running overtime as referees refer nearly every try for fear of getting the decision wrong.
New Zealand Rugby Union chief executive Steve Tew will attend an IRB council meeting this week and suspects the issue will be discussed both formally and informally.
"My personal view is that it is right and proper for Brett to be leading debate on this," Tew said.
"I know he's very conscious about 'brand rugby' and we have to get the balance on this right.
"We have to make the most of technology but not at the cost of rugby losing the unique elements it has."
The expectation at this stage is that most of the leading nations are in favour of the current trial laws around the TMO being retained for the World Cup.
No one necessarily sees the need for a major overhaul or revamp but all would be in favour of referees being given firm direction on how to best apply the laws at the World Cup.
