Is there already supported by JNA ? (If so I didn't find it) If not should I create an issue on the GitHub ?
I'm not aware of it. I don't think it is helpful to open a issue for this. The bindings were and are contributed by people needing them. In the past I needed improved COM support and so I contributed it. Others needed access to system information and contributed their extensions.
I doubt that people out there just wait for someone to ask for an API and jump to implement it.
