Yes I did submit the patch, years ago, for the reasons described. I
suppose that it would not be a terrible crime to allow cores to be
created as a option, but I think the basic logic holds - on a daemon in
production use, core can cause you real problems - by DOS if they take
up too much space, or too much time to write, or by providing a raodmap
to the clever hacker.
