The permissions management (user/group but with cloud roles) is what I miss most. NFS style approaches assume that I will give every user an unprivileged user on their local machine and deny root access so they can't just create a user with a different ID. S3 style ACLs per-object are just very confusing and no one is going to set those. S3 access policies per role are obviously not a solution because that requires centralizing lists of what the permissions are. I just want to be able to assign a chmod and a chown on a file for a cloud user and group... And don't forget about how fantastic the group tooling was.

I also miss being able to write files with /ttl=72h/ anywhere in the path and knowing they will be cleaned up automatically without me doing any more work. In contrast S3 just rots. Need to find an intern to write an SQS pipeline to schedule file deletions :)
