Agreed, but why is that a problem? 

The way I see it, the called function gets the address of the first element
in the static array and the compiler knows the layout of the array "[4][4]'
so why can't the called function use it like that? Currently, it seems like
an artificial restraint.

I can't see why this below should be hard to implement...

// -------------
void toFloatArray4x4(ref float[4][4] p)
{
    int n;
    n = 1;
    for (int i = 0; i < 4; i++)
    {
        for(int j = 0; j < 4; j++)
        {
            p[i][j] = n;
            n++;
        }
    }
}

void main()
{
    float[4][4] r;
    
    toFloatArray4x4( r );
}

// ---------
