Because that would be far easier to read and write:

   Input : String (1..1024);
   Count : size_t;
begin
   Count := fread (Input'Address, 1, Input'Length, File);

Or are you asking why anybody should use fread?

BTW, GtkAda binding consistently uses Address instead of storage elements
array. So it was not an idea of mine. (:-))
