S3 Files introduces native file-system semantics for Amazon S3—including permissions, locking, and incremental updates—addressing limitations of FUSE-based mounts (s3fs, Mountpoint). The change aims to let existing file-based tools work without rewrites, reduce auxiliary glue code (sync jobs, caches, adapters), and simplify building agents that read/write files and share memory.
