It also turns on trace, so it can be handy to find hard to debug problems.
In my case, it was helpful to find out why a delegate control wasn't rendering:
Tag(8e1n) Failed to create a user control from virtual path '/_controltemplates/CustomSearch.ascx': 'Microsoft.SharePoint.WebControls.SearchArea, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' is not allowed here because it does not extend class 'System.Web.UI.UserControl'.
