Comment(by dd32):

 First up, Disallowing local URL's into the RSS widget is likely to cause
 issue. there is nothing wrong with using a local url, but as with remote
 url's, if its incorrect, you can have issues.

 I know people who use the RSS widget to display their own feed for 1
 simple reason, The styling and HTML output is the same as that of their
 other feeds they have in that sidebar, It can go along way to easing
 styling if everything is the same.

 So, If there needs to be some extra catches in the RSS widget, like
 setting the max-redirects, or validating that the url returns a 200 only
 when set, Then lets do it.
