[wildfly-dev] how not to pass a JVM arg from host controller to spawned servers?

I noticed that whatever -D options you pass to the host controller (via HOST_CONTROLLER_JAVA_OPTS in domain.conf) by default also get passed along to all the servers that are spawned. If there is a specific system property that I do NOT want set in any spawned servers, how do I tell the host controller that? I simply just want to tell the host controller "The system properties named "abc" and "xyz" are *your* system properties only - they are not for any of the spawned servers to get. The other system properties you can pass down to the spawned servers." I'm hoping there is a way to do this without altering the host.xml definitions.
