It is probably relatively trivial to add a configure option to select just the "JRE modules" when building, rather than all modules. If we add such an option, it would still be possible to build a traditional JRE, not just at the same time as building the full JDK. Doing Erik's change as suggested here, combined with such additional functionality would allow us to remove a lot of old cruft from the build system, while still allowing distributors to build a JRE. I'd recommend doing something like this, rather than to delay this patch to post-JDK11. Removing old cruft is good. Also not building the jre image by default might reduce build times a little bit, a boon for those doing "make images" but never using the jre image (as the tests are run on the jdk image, not the jre image).

I don't have an opinion on whether configure option or a make target is the right approach. It might be that those consuming the jre image today are using the bundles target, a target that I wouldn't expect most developers will use when working on OpenJDK. Part of the socializing of this topic might be to get a better handle on what downstream projects and packagers are doing with the jre image (beyond creating install bundles for specific distros).
