Size could be beneficial for air-space industry. May be in transportation. For example, exist ships with special rotors for maneuvers, so this is possibility, to place somewhere very compact engine (or compressor), instead of bulky and expensive electric engine. For ground applications, I don't think this is enough beneficial, to be alternative to classic turbines.
