I think it’s fair to not call it equivalent because of that, but it’s also fair to acknowledge what is unsupported is pretty power user level stuff for the most part. I used spaces in s3 compatibility for a few use cases and never ran into the problem that what I was trying to do was unsupported. Granted I was not trying to do fancy things, but still.
Some examples of things that I used the S3 compat for that worked just fine:
- terraform backend
- velero backups
- log store for prometheus/promtail
- docker pull through cache
