I suspect we should just remove them. I'm sure they are useful in
theory, but I suspect they were more useful back when the whole "free
init memory" was originally done.
These days, if we have a use-after-free, I suspect the init-mem
situation is the easiest situation by far. Compared to all the dynamic
allocations which are much more likely to show it anyway. So having
debug output for that case is likely not all that productive.
