I would not be surprised if it turned out to be much more difficult than they initially expected.

Right now the primary way that "all quad" meshes are created by people is by arranging edge flows by hand in a sub-d modeling program, using the modeler's judgment and experience in how to best arrange the topology.

It's very difficult to replicate things that are based on that kind of intelligent judgment just with a list of exact instructions like a computer program is made up of.

The process for doing sub-division smoothing is fairly finicky too, it's quite easy to get a lot of messy results (with stuff like lumpy areas) in the subdivided results if the topology is not really well spaced and well formed. So I mean it's not even just having something technically "all quads" that's the problem - the thing you're looking for is more like "all quads with optimal edge flow topology same as hand drawn"...
