There may be a risk to the catalytic converters. They may need a stochastic fuel burn to make sure the NOx, COx and HCx chemistries work correctly. Also too lean may lead to an overload of NOx but I'm not a combustion or catalytic converter expert.
In Alabama it doesn't matter because we have no vehicle inspections. But if you need to pass an annual inspection . . . well you know the risks.
