I think that's the misunderstanding, then, because to me it seemed to be a defensive coding practice (I think it was certainly presented as such in the top comment). My "you need extra checks" claim was mostly aimed at the additional things you add on to your code assuming that you are now zeroing out freed pointers, which I think can lead to dangerous situations where you may come to rely on this being done consistently when it's a manual process that is easy to forget.

Left unsaid due to the fact I was out doing groceries this morning when I posted that was that I don't think this is even a very good practice in general, as I explained in more detail in other comments here.
