I think we can all agree when it comes to security, unqualified references to programs is a bad thing.

Thus, the reason IBM itself started qualifying references which broke the old trick customizing IBM
provided objects by CRTDUPOBJ to a library higher in the *LIBL.

I guess the argument is that I'd need to know the signature which is
easier to know for a srvpgm than an embedded module.

Assuming the service program is not explicitly qualified in the program
(i.e., using library list), putting a new service program higher on the
library list is trivial and the easiest thing to do, imo.

Doing an UPDPGM could work assuming you had the authority. This, however,
would probably leave incriminating tracks.
