In a word, no. In fact, if the pool is vinyl or fiberglass (or you live in an area with a high water table) draining ANY pool is not a good idea. A drained pool can pop out of the ground or the liner can be ruined unless special precautions are taken.
IF you live in an area that gets hard freezes a pool needs to be winterized but that is not the same as draining it. Since salt pools do not use stabilized chlorine then they do not become overstabilzed. The only reason water partial replacement might be needed is if the calcium hardness is very high and this often involves trucking in softer water is the supply water is very hard. (however, in areas with high calcium hardness, such as Arizona, there are companies that can 'process' the water in the pool to remover the excess calcium so water replacement might not be neceessary)
The water can be drained outwith a hose.
Yes, drained above ground pools are not structurally able to handle wind loads. The water helps the pool maintain its' shape.

A 15 ft inflatable pool typically needs to be drained and refilled every 5 to 7 days, depending on usage and environmental factors like temperature and debris. If the water becomes cloudy or develops an odor, it may need to be drained sooner. Regular maintenance, such as skimming and filtering, can help extend the time between drainings. Always check the water quality to determine the best schedule for your specific situation.
Vegetable oil is relatively to get out of a pool that is filled with water. The oil does not mix with water and will stay on the top layer. It can either be scooped out in a cup or the pool can be drained and refilled.
