Amazon-s3 is using the synonym s3. Now, S3 is also an object oriented implementation in R, but there is no way we can use that tag any more. Every time we apply it, it gets automatically converted to amazon-s3. How do we avoid that conversion?
I can see that this kind of collisions will only occur more often. Isn't it time to get a more strict policy on that tag-synonym thing? See also the FAQ entry on this
