No, the parent's university's apparent problem was that their DHCP was reallocating IP addresses soon after expiry. Dramatically increasing the pool size and the lease time wasn't the problem, it's the solution.
You're not wrong, but I'm saddened at this attitude. IMHO the tech giants already have so much power/ability to shape/force the standards to suit their own practices. The attitude of "Apple should be able to violate the standard all they want and it should be on network operators to accommodate them" is wildly empowering to the elephant over the ant.
