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."
Super League clubs need to change how and why they recruit players from overseas.
David Flatman has taken over the ownership of League 1 club York City Knights.
Leeds coach Brian McDermott says he expects hooker James Segeyaro to rejoin the club for pre-season training.

Wakefield Trinity have confirmed the signing of front row forward Craig Huby on a three-year deal.
