[wildfly-dev] can we get host controllers to push out subsystem extension modules?

<TL;DR> If I define my own subsystem configuration in one of the domain controller's profiles, can the DC/HC push out my subsystem extension module to the managed standalone servers just like it pushes out deployments to them? </TL;DR> In WildFly's Domain Operating Mode you can define Server Groups in your Domain Controller configuration [1]. In these Server Groups you say what deployments should be deployed on which servers, like this: <server-group name="main" profile="default"> <deployments> <deployment name="foo.war" runtime-name="foo.war" /> </deployments> </server-group> The DC and HC will do their thing to ensure those deployments are installed on the managed standalone servers. [3] Additionally in your Domain Controller configuration, you can define profiles with different subsystems [2] (so presumably some managed standalone servers can have some subsystems, where others in different profiles don't have to have them - or at least could be configured differently). For example: <profiles> <profile name="default"> <subsystem xmlns="urn:jboss:domain:web:1.0"> <connector name="http" scheme="http" protocol="HTTP/1.1" socket-binding="http"/> [...] </subsystem> <subsystem xmlns="urn:jboss:domain:fictional-example:1.0"> <socket-to-use name="unique-to-bigger"/> </subsystem> [...] </profile> </profiles> My question is - does the DC and HC manage that "fictional-example" subsystem extension module just like they handle deployments? In other words, will that subsystem's module get pushed out to the managed standalone servers (in the same way the DC/HC ensures the deployments are pushed out to the managed standalone servers?) If so, where do you put the module directory? On the DC, like deployments [3]? If not, how does this "fictional-example" subsystem that is defined in the profile make its way to the managed standalone server?
