I think because those were invented at a time when the operating system
facilities were less useful. And the log management facilities aren't
even very good, because there is no support for remote logging.

That is probably effort better spent.

I think the issues that you alluded to, what should be done in case of
what error, is important to work out in detail and document in any case,
because it will be the foundation of any of the other solutions.
