Minio started like that but they migrated away from it. It's just hard to keep it up once you start implementing advanced S3 features (versioning/legal hold, metadata etc.) and storage features (replication/erasure coding)

There's plenty of middle ground between "just expose underlying FS as objects, can't support many S3 operations well" and "it's a single node not a distributed storage system".

For my personal use, asynchronous remote backup is plenty for durability, a Bee-Link ME Mini with 6x4TB NVMe is plenty of space for any bucket I care to have, and I'd love to have an S3 server that doesn't even attempt to be distributed.
