Okay, thanks for the clarification.

The need is compatibility with JPackage. Our Java stack is simply not
big enough. Most of the Java packages in Fedora have gone in as direct
and indirect dependencies of Eclipse and Maven. In other words, JPackage
still has a large selection of directly usable Java apps.

*IF* we can convince JPackage to drop jpp, all would be fine. If we
cannot -- are we willing to lose compatibility?

Btw, there is also middleground that I haven't seen being discussed:
What if we drop the "jpp", but keep the X from Xjpp? So foo-1.0-1jpp
becomes foo-1.0-1.1 in Fedora.

This would maintain compatibility, and would give us numeric releases.

The above compromise would cause us to lose the ability to gather a list
of packages in the Java stack/common packages (with JPackage) though.
