Planning on getting one myself.

HANS is for neck, not compression of the spine. It's still going to cripple you.
The problem is the angle of the belt along with there being no crush support in the seat.
The shoulder belt is for holding you back, not down.
The lap belt is for holding you down, not back.
It's done this way because there is no chance of compressing your spine.
But even paraplegic's get IG likes so do as you wish.

Only separate shoulder straps are permitted. (“Y” type shoulder straps are not allowed.) “H” type

Now that is talking about 5/6/7 point with a cage, but the shoulder strap angle is the takeaway here. It's also pretty much a motorsport standard.
