There will not be a separate JSR for this work.  The specification and
the implementation will be developed in the OpenJDK Community and then
submitted for review and approval by the JCP for inclusion in a future
version of the Java Platform.

There will almost certainly be a way to determine whether code is
running in a static image vs. a full implementation.  I’d be alarmed
if there turns out to be a need for separate packages or modules.

I don’t expect there to be much, if any, processor-specific code here.
To the extent that there is then, yes, Oracle contributors would likely
focus on x64 first.  Contributions of support on other architectures
would, as usual, be welcome.
