I'm sure you are thinking of some specific situations, but in general I
do quick and dirty testing of many CEE APIs using CL.  One fragment is:

      DCL &DATE *CHAR 8
      DCL &LILDATE *CHAR 4
      CALLPRC CEEDAYS PARM(&DATE 'MM/DD/YY' &LILDATE *OMIT)

To simplify horribly, observability is great for situations like having
a program specify an 'ADD' and at different points in time the underlying
machine has a CISC ADD, a RISC ADD, and a floating point assisted ADD.
As the underlying machine changes (CISC to RISC; 48-bit to 64-bit;
N registers to N*M register) the machine can simply re-translate the
'ADD' to generate new instructions using new system facilities.  In the
case of a pointer vs a value on the stack however, it would be closer
to say the programmer went "oops", that 'ADD' really should have been a
'MULTIPLY'.  Observability does not help in this situation (and please,
no one go down the path that the machine could theoretically analyze
the stream to find the exact instances of the "oops" and change the
instruction stream because my earlier append really did gloss over some
of the finer points of what is happening in favor of expressing the
ending result).
