there's always more to find, but consider that this model is leaving out the environment entirely and its predictive value is even less than you might think at first glance. we know the environment impacts gene transcription, and we know that genetic determinism (as far as outcome phenotypes) is not a thing. likewise, there may be epigenetic factors at play which wouldn't be captured in a GWAS yet still might (or might not) have an impact on outcomes. it isn't a "the other lines of code are bug free" situation so much as a "we expect there to be an abundance of bugs with undefined consequences outside of the subset which we have examined which most likely outweigh the stuff we found"
