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."
Halifax coach Richard Marshall has ticked all the boxes so far in his plan to take the club forward, and is confident that Fax can become full-time soon.
As soon as Sam Burgess washed his hands of rugby union, South Sydney officials fell over themselves getting to the phone and the salary cap ready reckoner. It was, so the story goes, too good to be true.
