I absolutely agree. There shouldn't be any limit on short rests as long as you are out of combat and in a safe area, some chance of being found and attacked if you are resting in an area with enemies nearby would be good to handle the short rest in the middle of a dungeon situation. But allowing the player to select short rest and give them the chance to choose how many hit dice to roll to recover hit points during that short rest and track how many hit dice are being rolled would be ideal as opposed to limiting short rests to 1 or any other number.
