Unless you have undergone swing changes I wouldn't expect any change at all.
The lofts might be stronger which could make you think you've gained distance when you haven't.
10 year old cavity back irons of good quality aren't much different from brand new ones.

At the state government level, states can certainly do this, although several have banned covid passports. As to private businesses, the EEOC has already said that the private sector can require vaccinations of their employees, so there’s no real need for a passport. As to the federal level, I doubt Congress would pass legislation mandating passports because public health and safety largely falls to the respective states. Moreover, the White House is on record stating that there will be no passport mandate via executive order or a passport database.
