So the manual says to not add oil if it is low until it gets to the bottom line.

Coming from the old school of keeping the oil level filled at all times, why is the car company (Ford in this case) saying to not fill it to the full line until it goes one quart low? And will something go wrong if I do?

It just doesn't make sense to have a "full line" if it doesn't have to be kept full.

Because it's not needed and the auto makers don't want you to feel like you must add oil if it only needs 1/2 a pint. That and they don't trust the average person to not overfill the engine with oil. Me? If it's 1/2 way between the full and the add mark, I'm adding oil.

What does the manual say, verbatim?
Does is specifically advise against it?

I'm also in the camp of "1/2 way down, add 1/2 quart"

From the manual:
"Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil"

I keep it near the top. Why? Why not. If I go on a last minute 15 hour long drive I know that the oil is good, and not near the bottom.

Yup. Remember the pictures that everybody saw last week where washer fluid was poured in the sump?

There is nothing in that instruction that says you have to keep your oil at the MAX or FULL line either.

The manufacturer is saying that the MIN on the dipstick is sufficient to provide proper lubrication to your engine.

Sit back, enjoy your morning coffee and revel in the fact that the biggest worry in your life is whether to add 1/2 quart of oil or not.

In other words, LIFE IS GOOD.

My take on it is that if it is only down a partial quart, most people would not try to add only a partial quart, but put in the full quart, thereby having it overfull. Although I don't know about these new cars, but when I have had older cars that used a little (or a lot) of oil, I always filled them at least a 1/2 qt. overfull. My OPE I always fill a little over the full mark, and my stuff runs forever it seems, and never any oil related problems.

I'm torn on this for one reason. Is it likely that the dipstick lines are non linear and you'd end up over or underfilling ?

The full line is there for a reason. I like to keep my crankcase full. Some vehicles have small sump capacities. Why run your vehicle on 10-15-20% less oil?
