First of all that would take a Federal mandate or legislation. It tromps all over the state DNRs. Ain't gonna happen. In theory it could be enforced on Fed Property, but that ain't gonna happen either. Think about how much money the Feds take in every year on taxes on shafts .And it can't be a hazard type thing. Aluminum is safer than lead. Sounds like someone just starting something.
But say it is true. You likely won't be able to buy aluminum shafts in a few years anyway. It has been obvious for some time that Easton is going out of the alum shaft business. Maybe not tomorrow but it is coming. Used to be able to select from several numbers of shafts, now they are going to narrow that down to 4 or 5. At that point you may as well buy carbon since they will both have to be tuned the same way. If it takes the same time and labor to tune both and the prices are near the same, which way you gonna go ?. A great many of us want alum but in the grand scheme of things we are a small number. The compound shooters are driving the market. What they want will be what we have to buy. Or there is always wood .
