Just wanted to add some more justification to this (not sure anyone will look). 
The reason why I wanted this is because when I write out from Spark, to set the 
Object metadata after that via Java SDK APIs requires a copy of the object. I 
was hoping for a way to do this in one step that doesn't use the AWS CLI via 
shell commands form within spark, or other "hacky" things like that.

That's true enough. The use case on my end is that we use s3 object Metadata to 
get things like file delimiters, etc when we process files.

You can just set this with the S3 APIs directly? this borders or something it's 
not worth Spark passing-through just for S3 unless there's a common use case 
for it and possibly other FSes
