Yes and many of those were done.
The eat out scheme was about encouraging responsible behaviour too. Sitting down for a meal socially distanced, not cramming into a crowded bar. Many bars reoriented themselves to be more food led and more socially distanced as a result.
Hospitality needs trade and needs cash. Getting people to sit down and have a meal then leave is better than encouraging drunks to go on pub crawls.
As for bars there is no real distinction in licensing between a bar and a restaurant. Hence why when the government did try and say only with a meal for Tier 3 the media went crazy over Scotch Eggs. Because any bar can start serving meals and now it is a restaurant - there is no difference in licensing terms! Licensing is about the ability to serve alcohol, not the ability to serve food. You try to define what is a bar and what defines it needing to be closed.
Nightclubs were made to stay closed.
