I'm hoping that it won't be long before the web console is a separate download that merely connects to WildFly/EAP. At that point we would not ship web console with the server and this won't really matter any more.
I assume that if we do trim the console, it will be for WildFly only? That's probably a good thing but we would need to explain why the EAP download is so much larger.
Also note that localization is not just for logging messages and exceptions. Some DMR operations are localized too and presumably the result does show up in the web console UI.
