For me not being able to eat/drink on a typical EU flight sector would be no hardship tbh, and it has the benefit (if you've timed it well) of not having to use the lavatory onboard, thus reducing possible infection areas. The airlines, no doubt, would miss the revenue, but the CC would appreciate the reduction in workload and risk of infection as well. Most passengers other than diabetics etc don't need to eat on short sectors, it's mostly a Pavlovian response, Board Plane-----> Consume.
