We wish to propose jpackage as an experimental feature. That would give us the freedom to improve it incompatibly over one or two release cycles before it is commit to a final version.

There is no formal provision for experimental tools, in the same sense that there is for language features, but it will be sufficient to do the same in principal. We should use the option for generating the jmod described in JEP 11 (see the Description section). It should produce a warning whenever the jdk.jpackage module is resolved, and 'jpackage --help' should indicate that it is experimental and subject to change.

In the JEP, we would add [experimental] in title and in the Description.
