There is a lot of software that directly implements the HTTP S3 API. That API is also documented by Amazon.

E.g. the last implementation I saw was by DuckDB https://github.com/duckdb/duckdb-httpfs/blob/main/src/s3fs.c...

I think my point doesn't really land. I was trying to express the idea "S3 is not a standard where AWS is the reference implementation, it is a successful commercial product with many many copy cats".

Their only real inherent commitment here is to whatever backwards-compatibility expectations are being set for their first-party SDKs. If they fulfill that but other vendors can't or won't follow suit, the outcome is gonna be different than it would be for an actual standard rather than an assumed one. There is no meaningful leverage for the third parties to exert to force a community-favored outcome if Amazon decides otherwise.
