Our primary concern is ensuring that users have full control over the quality of media that's added to their library (so currently the API defaults to always uploading in original quality).
Clearly there are ways that problem can be solved, so please suggest this use case in the issuetracker and star the issue (so we have a sense of developer interest & you can be kept in the loop on updates).
