Featherstone chief executive Craig Poskitt says the dual-registration system is "bad for the integrity of the sport".
Rovers, minor premiers in the Championship for the past three seasons, have refused to adopt the system and a partner club, as have rivals Leigh, Sheffield and Halifax.
It has led to much criticism, but Leeds coach Brian McDermott said last week that he believed dual-registration is raising standards outside Super League and is good for the game.
Poskitt told the Yorkshire Evening Post: "It is not working.
"I think from Super League clubs’ point of view they will be quite happy saving six-figures per annum with no Under-20s.
"But it has been bad for the progression of the game and certainly for the integrity of the lower clubs, it is abysmal."
