After working in automotive, this is less impressive than it appears.
Tons of dimensions on 100k/yr injection molded(and otherwise) parts have similar dimensions. (Although admittedly, after testing in pre-production, I don't know if they are tested again and have drift)
Lego has been making the same parts for decades and their parts are extremely simple. I imagine their 1-off parts for intellectual property based sets do not have this requirement.
I think Lego has a huge incentive to promote this idea that they are high quality to justify the enormous price of decades old technology.
