According to the above discussion, from_uri is an enhancement for specific schemas such as http/S3/OSS, not for all current schemas. Can it be understood in this way?

Not exactly. I expect all services to be initiated from the URI. The discussion is mainly talking about whether to init services via a URI plus a map.
