I completely agree. If building a read-only fallback would require a lot of engineering and added a lot of complexity I would also say it is overkill, but as this solution doesn’t (happy to argue about that). It was an acceptable tradeoff for us as we already replica the underlying s3 buckets for disaster recovery as you already pointed out.

We also run our underlying Content Delivery APIs in two AWS regions so this was a logical extension.

If the added complexity is worth for your use-case can only be decided by you and I hope the article provided some guidance around that vs. just being a copy & paste gist.
