(I suspect this method also permits approximating the plastic number [ https://en.wikipedia.org/wiki/Plastic_number ], but so far it seems nobody has figured out a way to do so yet. I mention this due to the architectural relevance of the plastic number.)
I speculate that leveraging this fact could likely permit even more complex architecture in demos. (And, to mention an off topic point, it likely has some relevance for automating UI layouting.)
So many issues. First, that paper doesn't claim what you say it does. Second, it's just not a great paper. Even if we accept the sketchy premise, it fails to distinguish overfitting from a successful test. Numbers of the form (a+b*sqrt(2) can approximate almost any number to within 0.03 units, yet there's no discussion of fitting errors to address it.
The vast majority of ancient buildings follows quite simple procedural methods that only very recently got reverse engineered:
