>Almost no one is watching Sleeping Beauty for the first time whe they are fanfic-writing age, so there isn't that same shared sense of discovery. The style of character development is maybe more broad strokes, so authors might have to do more work to make a believable romantic relationship outside canon. You'd have to really be motivated to write something big.
Perhaps the image I chose confused the point: It wasn't about Sleeping Beauty, which is obviously totally different and not at all comparable to Frozen. It was about Maleficent, the live action movie that came out just ~7 months after Frozen and was a very similar subversion setup where the story is actually about the relationship between the two female leads, including culminating in "true love's kiss" being unconditional familial love rather than romantic love at first sight..
