I've found lots of scripts online to do it, but the issue is that we shouldn't really resort to scripting for this. CodePipeline already has a nice interface where I can choose the Elastic Beanstalk environment where I wish to deploy the code. Zero scripting required. Why can't they have a drop down where I can specify S3, and the Bucket name to deploy to as well?

After all, they offer S3 as a service where we can deploy static sites, so why not in their pipeline service offer an S3 bucket as a valid destination for the code?

My BitBucket pipeline I described above has less than 10 lines of YAML to define which S3 bucket to push the committed changes to, so already, a 3rd party workaround is 10x less code than your 'AWS only' workaround. This shouldn't be the case.
