Prior to this model, protein folding hadn't seen significant advancements in a decade or more. Worrying about the lack of tests in a first of its kind model is very much akin to complaining about the choice of font in a user manual for the world's first warp drive. I understand you're attempting to frame the problem in terms in things you know, but trying to weigh down pioneering research with professional development ceremony is very much counterproductive. The 'missing' ceremony would not have contributed to the strength of AlphaFold's result, the model's only purpose was to compete within the context of an existing validation framework.
