Like you were scheduled to depart at 4PM and the flight is now delayed to 11PM and you don't want to wait around.
I guess I didn't understand you
That's assuming you're not starting from your "home airport. Also, in the event of a missed connection the gate agent may tell you to fly to the connecting airport and get hotel/food vouchers there, never a good idea. If your flight is massively delayed you may be given the opportunity to rebook the next day without fee/refare but hotel and food would be your responsibility.
Why does home airport matter versus not being at home airport? For all they know you drove 3 hours to get there.
Why would rebooking the next day change whether or not they cover accomodation? That's the only case I would expect them to cover accomodation.
