I think you are going about this in a bit of a confusing way :) If you 
wanted to propose the ZGC feature check should be OS agnostic then you 
should have just proposed that rather than proposing a Windows-Aarch64 
change that clearly belongs with the port work. You'll need to discuss 
the ZGC check with the ZGC folk on hotspot-gc-dev (now cc'd) but I'm 
pretty sure the OS check is deliberate, so that only those platforms 
known to actually work will be enabled.

Thanks,
David
