Thanks for the link, I hadn't been there.
I think mostly this part: "Science Fantasy works, on the other hand, take traditional Fantasy and Science Fiction tropes and throw them in a blender, purposely creating a setting that has the feel of both."
The stuff in my memory doesn't feel like much on the rest of that page, and as the page notes, there certainly exists more than a little "Sci_fi with a smidgen of Fantasy".
Further down in the examples it has:
"Dune by Frank Herbert series is science fiction, but apart from ‘’Star Wars'' it might be the best well-known example. The Galaxy has an Emperor and several rival feudal-aristocratic families rule over even complete planets. There is a quasi-magical order of witches, although the story is otherwise within a fairly straightforward interplanetary science fiction setting."
