Good point, prefixes are performance boundaries too, per-prefix rate scaling means you can spread load across prefixes to get aggregate throughput well above 3.5k RPS [1].

But that's a different thing than what the post is about. Even teams that use prefixes for performance don't have an S3-native way to ask what a prefix represents, who owns it, whether it's still accessed, and so on. The semantic layer is missing whether you're hashing for throughput or just laying data out the obvious way.

Absolutely right and if I disagreed with any other point I would have said something, a very solid post about metadata in general I just dont want people to ever leave with a "oh well we can just put it in one prefix because it MEANS the same thing" because that way is slow and bad.
