Incorrect words. I just mean that there is a central code path used by
DEBUG and FATAL in this case, and DEBUG is controlled by a user-side
switch, meaning that if we want to get into something aimed at being
used by any in-core or community frontend clients, we are going to
need something carefully designed.
