There are so, SO many teams that use S3 for static assets, make sure it's public, and copy that Object URL. We've done this at my company, and I've seen these types of links in many of our partners' CSS files. These links may also be stored deep in databases, or even embedded in Markdown in databases.
This will quite literally cause a Y2K-level event, and since all that traffic will still head to S3's servers, it won't even solve any of their routing problems.
Set it as a policy for new buckets, if you must, if you change the Object URL output and have a giant disclaimer.
But don't. Freaking. Break. The. Web.
