This isn't for your URLs. It's for URLs you're linking to that you don't control and that are liable to change because other people (typically large content sites) don't understand how URLs should work.
Now what? What if the newspaper.com URL changes? Am I supposed to keep all my URLs up-to-date (i.e. send pull requests every now and then to update my "bookmarks")?
web.archive.org seems much more useful, by copying the entire page at the time of creating a snapshot and thereby creating a true, durable copy.
