I believe clang is already extending const power in more scenarios.

https://godbolt.org/z/h1ha5jfPn

struct X{
     int i;
};

int main()
{
   const struct X x2 = (struct X){.i=1};
   static_assert(x2.i == 1);
}


https://godbolt.org/z/EW797PjEq
struct X{
     int i;
};

int main()
{
   const int a[] = {1, 2};
   const struct X x2 = (struct X){.i=a[0]};
   static_assert(x2.i == 1);
}
