I have integrated weight pockets. The pockets can be removed separately so it is possible to drop just one pocket. Actually if time s I can remove a pocket, remove a weight from it, and then ascend either holding the remaining weight or reinserting it and clamping it in. Sometimes I wear dive shorts. Fun exercise is to take off gear and put it back on. I remove weights and put int short pockets then easier to take off and don the equipment again. Then put weights back into jacket. Avoids the problem of being light and floating over heavy equipment.
Point is there is lots of flexibility in how much weight is shed and kept.
