Filling up when gas light comes on...

Here's the truth about this topic as it comes up periodically and this misinformation is spread anew.
It does absolutely no harm to your fuel pump or injectors or any other part of your car to use all of your gas. Period. There's no trash or water in your tank. It doesn't make the pump hot. It does no harm whatsoever. There is quite a bit of reserve fuel even after the gauge says empty and the distance to empty says zero. At least 2-3 more gallons.
I have 81K miles and I almost always run it very low. To 0 miles left and beyond. Routinely. I opened my tank on both sides. Clean as a whistle. The pump is cooled by the cold gasoline running through it any time it pumps fuel. As long as there is any fuel being pumped its being cooled.
Run it as low as you like as often as you like. Just don't run it completely out and keep trying tu run it dry by continuing to try to start it after its dry.

Yep, I know the capacity is 20 gallons. I've run it to nothing on the meter and the needle on E but haven't filled up at that time to measure it, just put $20 in at the time. UGH! This is annoying because I'm one of those people that likes to stretch whatever fuel I have if I can comfortably make it. No other car I've owned or spent any real time in has shown such a false high level. 2-3 gallons is a lot of "reserve". I know the owner's manual uses the term reserve but usually in other vehicles that refers to the amount left when the low fuel warning light comes on, or when the needle is in the red zone (which the G does not have).
I guess the only real way to find out is put a spare gallon or two in a can in the trunk, run the thing dry while noting roughly how far I can go on the warning light. Put in what I have, drive to the nearest station and fill up.
Anyone ever run out? Any negative consequences??

Running on empty: Low gas in the tank can be costly
i have never had a problem with my fuel pump so i cant say what it true or not.

I've run out of gas in previous cars and didn't mess up the fuel pump. Perhaps I should be more specific, any problems getting it restarted after running out? Or in some cars, the tank will collapse in on itself.

Is it true that when low levels of gas brings all the sediments that settle in bottom of tank & filters thru car?

I recently ran my car to nothing on the range meter and the needle just barely above the E. Filled up and it took a little over 16 gallons to the first gas pump auto shut-off. Thought it would easily take another gallon but never got beyond 17, and that's topping off until fuel starts coming out the filler tube. I'm REALLY curious if the tank is in fact a true 20 gallon capacity.

I always go well past the range indicator and don't really pay attention to the E on the gauge.
I reset my instrument cluster mpg indicator every tank... so the mileage it shows me is the mileage for that tank. If the gauge is reading that I'm 22.6 mpg, then with a 20 gallon tank I'm good for 452 miles. You get the idea. So I always take my car over 400 miles on one tank and get pretty close to the calculated number, and the most gas I have ever put in the car was 18.6 gallons.
I am not convinced over anything anyone has ever said about sediment in the tank or overheating fuel pump.
I got to look down into a 120,000 mile Miata fuel tank with a lighted boroscope once. It was pristine inside there.

I always fill mine up at about 1/4-1/2 remaining. From what I understand, the gas helps to cool and "lubricate" the pump. That is not my concern though. I am really more concerned about living in a freezing cold state and being stuck somewhere with less than a 1/2 tank. Just want to be able to run the heater to keep my family and myself warm.
