S3 Uploader exposes S3 URI to the public
I have a private S3 storage that is not intended to be directly accessed by end users. When using S3 storage the "public_endpoint" setting causes the URL posted with image files to leak the private URL of the storage and cause issues by not being directly accessible.
A dirty hack / workaround is to create a new domain for the "public_endpoint" and proxy this through your webserver, but it's not ideal. If we could force local media to go through the proxy it would be a better solution.
