As I've commented on the bug [0], I don't think a new project is
necessary to provide OS support for an architecture port, when the port
already has its own project (aarch64-port), and the developers involved
in adding support are already working with the people involved in said
project. After all, the ppc-aix-port project seems to have branched out
quite happily beyond AIX ;-)

A JEP does seem appropriate though, so the work is listed in the release
notes of the next JDK release.
