Parmlib concatenation to prevent upgrade erasure?

[1000TurquoisePogs]

When a ZIS plugin installs, it may need content in the zis parmlib.
When zowe upgrades, this parmlib gets reset.
Can we concatenate parmlibs so that we can have a plugin parmlib separate from the zis core parmlib?

Specifically:

In order to copy the Zowe load modules from the new Zowe version into zowe.setup.dataset.loadlib and zowe.setup.dataset.authLoadlib, you have to run:

zwe init mvs --allow-overwrite

Unfortunately this overwrites zowe.setup.dataset.parmlib(parmlibMembers) (a.k.a. ZWESIP00).
Third party plugins like IBM Unified Management Server will append parameters to ZWESIP00, but they get overwritten.

It would be great if the ZIS and ZIS AUX servers allowed parmlib concatenation just like the Zowe launcher.
Alternatively, an upgrade of Zowe should not overwrite ZWESIP00, but merge instead.

We need to investigate this further.

I can have a look and see what could be done from the ZIS side.
