sure about that?

  struct a a;
  struct b b = *((struct b *)&a);

And before you complain that this is more than adding a cast, consider that
this is also an error of the exact same type:
  struct a a;
  struct b b = *(&a);

Further I also assume that you don't see compiler warnings as disagreeing
with you? like in

char *a;
int b = a;
# warning: initialization of ‘int’ from ‘char *’ makes integer from pointer
without a cast [-Wint-conversion]
