The low work environment can change within a second. Then you end up with one person having to deal with a situation that needs at least two. One flying and one to see what is going on and what to do next. And the one guy left can collapse or be hit by cockpit window shrapnel or similar and be knocked out of duty as well anytime.
It is not responsible to plan like this.
