There are tons of these tricks you can use to cut costs and get resources for free. It's smart, but not reliable. It's the same type of hacking that leads to crypto mining on github actions via OSS repos.

Treat this as an interesting hacking exercise, but do not deploy a solution like this to production (or at least get your account managers blessing first), lest you risk waking up to a terminated AWS account.

I have used this and other techniques for years and never gotten shut down. Passing through S3 is also generally more efficient for distributing data to multiple sources than running some sync process.
