It can, and it does. CICS, DB2, MQ for example. The installation instructions tell you the security requirements and adding the new names is just part of the process if you don't use static names. >As a general rule, our non-z/OS target DSNs (i.e. true names) include a >version-release-level qualifier.

If all you do is create the library and then copy from old-version to new-version for all the modules or most of them (without out re-asm/link), then what is the benefit of having them live in a release specific library? I can tell you that I usually like a combination of both. A library for the sort of thing you are doing that has a static name where the modules don't (normally) have any release dependencies, and one that does for release dependent modules (like JES2 exits).
