The same section says
     "The permissions granted by this clause can have an effect on the
      semantics of a program only if the program fails a language-defined
      check."

So unless you're coding in a way where you expect to cause and catch
l-d checks, it won't matter.

Also, if I read that section correctly, in a sequence of code like this
     a := 0;
     b := c + d;
     e := f + g;
     h := i + j;
     a := 1 / a;
it is possible that only the assignment to a will have occurred when the
exception handler from the division by zero is executed, is that correct?
Doesn't that make catching failures of language-defined checks useless?
You will know that something bad happened, but you won't know which objects
in your program are abnormal.
