Review Comment:
I did some research about the names used in cloud providers
S3 uses the term `If-None-Match` for the "don't overwrite" method:
https://docs.aws.amazon.com/AmazonS3/latest/API/API_RenameObject.html
From what I can tell, GCP doesn't support an atoimic rename/overwrite
operation. If you want to overwrite you have to delete the target first :
https://docs.cloud.google.com/storage/docs/copying-renaming-moving-objects
Azure Blob Storage calls it "replace if exists", specifically
https://learn.microsoft.com/en-us/rest/api/storageservices/rename-file
`x-ms-file-rename-replace-if-exists`
So TLDR I think these options are well named and reflect the available
capabilities 👍
