Yes it is. I've only come off a handful of times, but I never noticed my feet being trapped - after a while it becomes almost a subconscious action.
Toeclips are considered more dangerous as you often need to loosen the straps first to free your foot. I know one person that broke bones in his foot when riding up a curb at the wrong angle (i.e. wheel slips) when using toeclips. (I also hurt my wrist when using modified toeclips on a unicycle and didn't get my foot free in time).
They're still in use, but probably more likely on a fixie than a road/racing bike.
