I've given it thought, but it just seems like a lot of work that you don't really need. You can keep the entire setting without the timeline, or include the timeline events but just say the White Council handled it. That sidebar with problems that only Harry Dresden could have solved pretty much ignores a GM's right to drop random characters wherever and whenever she wants - pretty much all of them, for instance, can be handwaved with "the White Council found out and stopped it".
If you're actually going through the story events, then you might have an issue, and then the sidebar might be helpful.
