This may be useful if there are any OP1-based boards whose associated voltage regulators are unable to deliver the exact voltages; otherwise, it causes no functional changes to the resulting OPP voltages at runtime. These changes cannot cause stability issues or any kind of damage, because it's perfectly safe to use the highest voltage from an OPP group for each OPP in the same group. The only possible negative effect of using higher voltages is wasted energy in form of some additionally generated heat.
