alt Hacker NewsS3 isn't "simple" tho.
It doesn't need to care about POSIX mess but there is whole swathes of features many implementations miss or are incomplete, both on frontend side (serving files with right headers, or with right authentication) and backend (user/policy management, legal hold, versioning etc.)
It gets even more messy when migrating, for example migrating your backups to garagefs will lose you versioning, which means that if your S3 secret used to write backups gets compromised, your backups are gone vs on implementation that supports versioning you can just rollback.
Similarly with password, some will give you secret and login but won't allow setting your own so you'd have to re-key every device using it, some will allow import, but only in certain format so you can restore from backup, bot not migrate from other software.

The author is also not really clear on what they are actually needing.
If they just want webfile interface then a webserver with simple auth and webDAV would work more than well enough.
The problem is that they then go onto talk about lots of projects that all have posix interfaces. Which is slap bang into shared filesystem land.
S3 is not a filesystem, and nothing shows that more than when you use it as an object store _for_ a filesystem.
Depending on the access requirements, if you're doing local to local, then NFSv4 is probably more than enough. Unless you care about file locking (unlucky, you're in shit now)
I just spent some time with the s3 protocol and I agree completely. What should have been able to leverage the simplifying assumptions turned into another hodgepodge. It’s not like nfs is a real shining example of simplicity either. I’ve never worked with p9, but potentially that aside I think we really failed to come up with a decent distributed file model,
S3 needs a split:
QS3 (Quite Simple Storage Service) for the barebones. Bucket/Object CRUD. Maybe: Multipart Uploads. Presigned URLs.
S3 for Object Tagging, Access Control Lists, etc.
S3E (enterprise? extended? elaborate?) for Object Lock & Retention (WORM compliance, Legal Holds), Event Notifications and so on.
