   > Could you move it into a new "Upgrading to Comet 1.2.0" section and say 
that 1.1.0 and earlier addressed these endpoints path-style?
   
   Moved in c5594463b. The entry also covers the no-endpoint case with your 
`fs.s3a.endpoint.region=us-east-1` example in both directions, notes that 
host-matching proxy or egress rules will see the new hosts, and says native 
Parquet and CSV scans, since native Iceberg reads go through iceberg-rust's 
FileIO and are unchanged. The description has the same case.
   
   > Could you move the new block above the `extractObjectStoreOptions` 
scaladoc?
   
   That block is gone in aa73a0d6c: Hadoop's profile provider now resolves 
through `HadoopS3ACredentialProviderAdapter` on the executor, so the JVM no 
longer forwards a default credentials path and `NativeConfig.scala` is back to 
main.
   
   > If we keep these, could this row say so?
   
   Neither is kept. Hadoop's provider picks the STS region and endpoint now, so 
the row describes the routing instead, and the S3 credential provider guide 
covers the class-loader requirement, the explicit class and the blank opt-out. 
The AWS SDK `ProfileCredentialsProvider` names still resolve natively as on 
main; their differences from Hadoop are tracked in #6575.
