What use case made this cause an issue for you guys? My go-to resolution here is just to use immutable files (sha256'd filenames typically), though that does entail storing separate keys for every related object

We host a lot of files and we do need permalinks to them. We also need updates to be visible immediately for everybody.

That's fair. Anything you don't need to resolve as redirects/file serving through an app is a big win

Have you ever tested S3's eventual consistency? Just curious.

There's no explicit SLA, but I've heard rumor that they start getting paged at ~4 hours staleness, though that might not be actually-true. I would think it's pretty quick in the average case.
