Considering the stuff we sell could have significant impacts to one’s health… I take QA very seriously.
True… but a slow reduction to 20F or whatever your freezer it set at (and not thermally cycling them too much) is not all that insane… and keep in mind one of our stress tests was tossing chips into liquid nitrogen… 10 out of 10 chips testing in LN₂ came out alive and kicking 
But of course this is the case so no need for freezing.
