Risking dangling pointers is much worse than null pointers as that can
lead to memory corruption, which may be difficult to detect under normal
operation. Crashes triggered by null pointer dereference are typically
much easier to debug and fix.

If you're sure that the object is still valid after the ownership
transfer, it might be better to not transfer ownership at all or
postpone the transfer.
