As a DoF "hater", my problem with it is that DoF is just the result of a sensor limitation (when not used artistically etc.), not some requirement of generating images. If I can get around that limitation, there's very little motivation to maintain that flaw.
In the real world, if I see a person at the beach, I can look at the person and see them in perfect focus, I can then look at the ocean behind them and it is also in perfect focus. If you are an AI generating an image for me, I certainly don't need you to tell me on which parts of that image I'm allowed to focus, just let me see both the person and the ocean (unless I tell you to give me something artsy :)).
