Perfect form isnt a thing, its all a matter of what joint positions you are adapted to produce or reduce force in. So the problem with form breakdown isnt that the position you end up in is dangerous (no, rounding your back some is not bad), but that you are not prepared for the stress in that position.

Its unfortunate that people say deadlifting "wrong" causes injury, while the evidence does not support it. People should not be turned off from lifting heavy by such statements.
