The University of Minnesota Twin Cities offered Gmail to students when I attended '11-'15. They allowed alumni to keep the account and I respectfully used it, though infrequently, and kept my account active with reminders to log into it every 90 days. Late last year they claimed that Google was beginning to charge much more for accounts, and those alumni accounts were going to close.

This isn't the same as the forwarding service, but maybe the overhead wasn't worth it anymore.
