ASUS pointing out that they are defining new rules for vCore and SoC voltage to address these issues is in fact pointing to that as the issue. They aren't just "throwing that in there" because it is unrelated. If you need it to be even more direct, here is the statement from ASUS that says it is SoC voltage.

Here is the statement from Biostar that says SoC voltages are being limited:

You've admitted that you work for AMD, which would make a casual observer think that you are being biased in your comments. There is verifiable proof of the correlation with SoC voltage from the ODMs themselves.
