Isn't having the parents make the decision to stop or go some sort of Standards & Practices requirement?
Actually, the show sounds like the planned (but dropped in favor of WWTBAM, as I recall) The $640,000 Question (I wonder if they are considering getting Ben Stein as host?).
Speaking of which, here's why I think having the parents make the decisions is a requirement: back on The $128,000 Question in the mid-1970s, when they had minors as contestants, they specifically asked the parents if their kids would stop or continue.
Also, on Joker! Joker!! Joker!!!, that must have been the reason they had one of each winner's parents play the bonus round.
