Eh, wut? I doubt this very highly. I believe that some schools are choosing to move towards multi year scholarships but if they can still choose how long they want them to be. If they have an extra scholarship being unused due to a player transfer or whatever, they can still award that to a walk on for the season and then have that player go back to being a walk on the next season. Otherwise, teams would just burn the scholarship so they aren't stuck having to give it to that player for longer and that would be ridiculous.
