What are your thoughts on the 'horse suit'?

I'm not quite sure what to think about this idea so I'd like to hear what people think. The idea is easiest to explain by explaining how it would look: it would like a diver's wetsuit attached to a horse. The idea is that a rider wears the suit when riding and thus cannot fall from a horse. I'm kind of thinking it's a good idea but I'm not sure! Would it be dangerous? Would it have some actual applications or is just an interesting thought experiment? Would like to hear general thoughts, applications, or ideas generated if this is treated as a 'What if?' thought experiment
