I mean, they're not even willing to deal with the question of whether we have a right to bear arms (cert denied in the NY state may issue appeal). That said, it will get very interesting when Illinois goes full Constitutional Carry on June 9th, or, well, after the District courts enjoin the state from enforcing its unique besides Hawaii absolutely no issue law. And we'll have to see if they and the Circuit court will play wack-a-mole with all the localities that will ban or unduly restrict concealed carry.
(In theory the legislature could fix this, but a supermajority is needed to override Chicago home rule, and that's not happening. And the most the rest of the state is willing to give to Chicago failed.)
And thus we have a circuit split, with another decision from Maryland being appealed to the Supremes.
This being in the US constitution only indicates that society in the US finds this rule very important. Putting it in the constitution makes it hard to change or abolish the rule.
Hard to change is different from unchangeable, though. Extreme example: if the constitution were unchangeable, slavery would not be constitutionally prohibited.
So, this is up to society.
