I think, that this exercise is safe when performed safely, but if enough
people would do it, there would be quite a number of those who injured
themselves with this thing. Why not simply do behind the neck jerks?
Or push-jerks, for that matter? What is the advantage of your version
of squat over those proved and effective exercises? Higher loads,
maybe, but addition of real squats would obviously counter this slight
advantage totally.
IOW there are reasons why some exercises are done very rarely. They are
simply not worth being done more often.
(Though I have to admit that I've seen record holding high jumper doing
something similar. He didn't try to jump as much as performed very
explosive and very shallow "squats", his heel breaking contact with the
floor AFAIR, but not really jumping. Too much at stake if he landed
incorrectly? Possibly.)
