A properly adjusted bike with the right components allow you to brake easily in the drop position. On one of my two touring bikes, four fingers curl around the brake levers when I am in the drop position. On my other bike, I must bend my wrists to get my fingers around the levers, or be content to brake with two fingers per hand. So on the second bike, I use the drop position less often.
Although I ride in the drop position infrequently, it is nice to have the option. Postural variety is good for all-day comfort.
