I looked at the WFC recently ("Level generation and style enhancement - deep learning for game development overview", https://arxiv.org/abs/2107.07397).
Yes, it is a big inspiration, and there are numerous beautiful examples of its results. However, the QM wording is at best an extremely loose analogy (one that a hacker would use). If you want to compare it to other methods, see "WaveFunctionCollapse is constraint solving in the wild" https://dl.acm.org/doi/10.1145/3102071.3110566.
