I heard back and there's even more confusion -- we were tracking an older copy 
of the DR list, and there's an update that clarifies this: 
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2396.htm#dr_496. So you're 
right, the array and member access extension warnings need to be removed. I'll 
take care of that and get it cherry picked into the Clang 16 branch.
