Removing observabiliy (was: Reason not to go to V6R1)

["Mark S. Waterbury" <mark.s.waterbury@xxxxxxx>]

How many vendors still remove observability?

Since the CISC-to-RISC transition, removing observability does not save 
as much disk space, since the RISC instruction stream is so much larger 
than its IMPI equivalent, so the percentage saved by removing 
observability is lower. And, since V5R1, removing observability only 
compresses and "hides" the creation data, so the template still takes up 
considerable space.

To protect "intellectual property" and make it harder to 
"reverse-engineer", with ILE, New MI is not documented outside of IBM, 
so it should be far more difficult to reverse-engineer a program from 
the NMI template (compared with OPM MI). This is another good reason for 
vendors to move away from OPM and covert to using ILE languages and 
compilers exclusively.

IMHO, there is no longer any reason to remove observability.
