I doubt that there's actually any safety issue here, though it may be required by regulations which claim to be on grounds of safety.
In the roughly half of he world which has a single phase Voltage of around 240V dryers, cooks etc have lamps, moters, electro-mechanical timers etc. operating on 240V without large numbers of people being killed by them. At one time there was probably an issue of being able to use standard, readily available, parts, but these days the same factory, probably in China, is likely to be making components for use in many different countries, with different Voltages. Also, these days things like timers are likely to be electronic devices operating on a few Volts d.c., and this could be derived just as well from 240V as from 120V, so there's probably no great advantage in having a neutral available these days. There is an advantage to 120V for small incandescent lamps are concerned, and 120V ones are certainly more readily available in the US than 240V ones, but I doubt that it's really a safety issue. You could always use a 12V halogen lamp.
