It still might be doing something. Mail, for instance, is sitting there occasionally checking for new mail even if you have zero windows open. And I dunno about you, but my 2017 Macbook Pro still takes a significant amount of time to launch Big Serious Apps with a ton of plugins. I like being able to tab over to Illustrator and hit command-n and be fucking around in a new canvas with absolutely no waiting. We have virtual memory, open apps in the background doing nothing but waiting around to be used will get frozen to disc, then get restored a lot faster than they boot up. I generally hate it when apps auto-close themselves without asking when I close the last document like Windows tends to.
