To me it just seems like this rule was put in place because rich schools were losing 5* bench players to less-rich schools because there was not enough room for them at the 5* hotels. This can mitigate that ensuring the teams that simply reload and compete for championships can continue to do so more easily while programs that rely on consistent player development and teaching 3* how to be 4*+ can continue to grind and grind and grind seemingly in place and then when a once overlooked recruit breaks through there is now plenty of room for him at Blue Blood Asshole-atorium U. (pre-season ranked top 15 after a 3 loss season) thanks to the new lax portal, and the cycle can repeat into infinity.
That's just my take though.
