Are you proposing that instead of building a single JDK distribution with multiple JVMs, they would build a separate JDK for each alternative JVM configuration and publish java.base.jmod from each of them for end users to pick from when generating their run-images?

I think there is a compelling case for having a release + fastdebug build of a server libjvm in the same run-time image. I'm dubious about server + minimal in the same run-time image, it's just too weird unless users of minimal VM are also running with `--limit-modules` to use a reduced set of modules before running `jlink` to create the target run-time image for the small environment.

For embedded environments  then it could be compelling to have the the packaged modules (JMOD files, and not just java.base) published for several OS/architectures. There's a connection to cross building here. Once you have the packaged modules then someone could run `jlink` (on a main-stream platform) to produce the run-time containing the small set of modules that are appropriate for the target environment.
