Yeah, pretty much. It really might not be worth it which is why I wanted to bring it up before I continued down the path. Maybe one idea would be to exclude only things like the logmanager, but allow transitive dependencies for org.wildfly and probably DMR and MSC.

The two client jars that were an issue actually weren't a result of anything in WildFly. I just started going through it and opened this lovely can of worms.

That would be awesome. Like a compile scope that actually means, I don't know compile not runtime :)
