If Marriott did extending status for everyone, is just to prevent customers being poached by competitor.
As for people who still travel despite the situation (myself included although just local travels due to my work) Marriott could do double night or/and point promotion so they can get higher tier and extra 50 and 75 options if they are below ambassador.
For ambassadors then.bad luck unless marriott willing to gift 1 year cobalt for these
