Sometime ago, i tried react and found a property named like "do_not_modify_or_you_will_be_fired" (i dont remember in which object).

I understand encapsulation is necessary, but i wonder how feels working with someone who writes code with a shotgun next to him / her.

Not sure what your point is about th shotgun. The point of that export is to keep supporting old API with a deprecation warning while it is being moved into another package. It is temporary.
