Not planned. But you can do it yourself easily enough. Grab a copy of jboss-seam-jul.jar from lib/interop in trunk, put it in your JBoss AS, and copy the FaceletsJBossLogging.class into your WEB-INF/classes along with a seam.properties.
I got it working, thank you. But to be a bit more precise:
- copy lib/interop/jboss-seam-jul.jar to $JBOSSHOME/server/default/deploy/jboss-web.deployer/jsf-libs/
- copy FaceletsJBossLogging.class into WEB-INF/classes/org/jboss/seam/ui/facelet/
- copy seam.properties into WEB-INF/classes/
