One thought...

I can easily imagine situations, e.g with cameras or acquisition cards,
where a low-level driver (maybe shipped as binary) provides a new
pointer to an array with every callback. I would really like an array
record to be able to use this driver-allocated buffer, without copying,
hopefully up to the network layer.
Restricting the out-of-bounds-offset hack to one allocated chunk of
memory would not serve this case, would it?
