Support for NUMA APIs will be addressed in a separate workstream as part of [JDK-8244065: Implement NUMA support on Windows](https://bugs.openjdk.org/browse/JDK-8244065)

Hi @dholmes-ora, what is the expected approach for adding flags for a feature like this? https://wiki.openjdk.org/display/HotSpot/Hotspot+Command-line+Flags%3A+Kinds%2C+Lifecycle+and+the+CSR+Process states that product flags are considered exported interfaces that require a CSR request when they are added. Does the flag need to start out as an experimental flag or is it okay to just add it as a product flag for opting in and then going through the CSR request immediately?
