Very interesting topic. I think this is a style issue. Why are there so many styles of furniture, shoes, cloths, cars? If it floats your boat, go for it and get the job done. Personally, my quilts are expressions of me and I'm always out of the box. So how often does "cute" fit into my style. So personally, most embroidery designs are not my style. Having a Bernina 830 with the embroidery unit seems like an oxymoran. It does have some uses, like quilting 24 traditional blocks exactly the same. And having studied designs I've found some that border on my expressive style.
Sorry I can't find who posted this, "I've seen quilts with embroidery, both hand and machine, that I didn't think enhanced the design, and I've seen quilts where embroidery accents have elevated a hum drum top." I agree that all details on a quilt should enhance the quilt, not just be stuck on there. But again that's my style.
So every one to their own opinion.
