Most of it, but don't take it personally. All RO units should have an auto shut off unless they are the portable units which are only hocked up to a water source when needed. I wouldn't say that's the norm most units are permanently hooked up to a water source and the shut off valve is on the output. This being the case it will require an auto shut off whether a pressure storage tank is used or not.
The basic rule is to never rely on mechanical floats. I believe humidifiers have a drain if the water level gets too high, same as a toilet. Electronic systems can be designed with unlimited safety systems to prevent failure so you actually design them to meet your own personal confidence level.
