The publishing part (in Moodle) should be fine.  It's the hub that is no longer supported. 

However, that kind of sharing doesn't give you very much - it effectively just posts links with some metadata to a central place.   Any user that wants to go to a course on another site will still have to log in there etc so you'd need to organise OAuth or something as you said, more manually.
