Yep, I don't know..... In every package I've handled in my life, linked images are a life savior when you are creating things like board/card games, and many types of publications or general designs, where an image is reused in the design (one design even calling many linked images) a lot, and you want to independently edit that image, have it always up to date without needing to re-embed it... But it's maybe just my usual workflows. In the other side, being able to embed is often important, too...
