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.

Proposal to rename the services:

* S4: Stupid/Silly Simple Storage Service

* S3: Simple Storage Service

* S2: Storage Service

You can't have the numbers go down like this. Try pitching S2 to your project manager. You will be told 100% "Why not use S4 instead, that sounds better"
