As others have mentioned, this is "just" constraint propagation. I think much of the success is that it's a simple idea to grasp and implement, that provides very good results, and has a compelling name. I don't want to be dismissive, I think it's very cool. The original author of "wave function collapse" also has "convchain" [0] which is similarly "just" using Monte Carlo Markov Chains to sample the space. It's also a kind of "staple" algorithm for physicists, theoretical computer scientists, etc but I guess hasn't caught on as much as WFC. Note that WFC has major problems when the tile set is too constrained. There's a SO question about it [1] and I also happen to have written a small article about it as well [2]().
