The reason for not doing it in the structure determination is that we don't know the classloading rules until much later. Parsing jboss-classloading.xml in the structure deployers is not an option because the rules can come from legacy deployment descriptors and anybody could write their own deployer to create or modify the classloading metadata in an ad hoc anyway.
