If you mean Hibernate 5.x specifically, we started the integration on 
https://github.com/scottmarlow/wildfly/tree/jipijapa3_hibernate5

You are complaining a lot lately.  We purposely designed for known use 
cases.  There are other ways to get the dynamic environment that you are 
looking for then complaining that the WildFly JPA subsystem 
"jboss.as.jpa.providerModule" option doesn't work.

The question is whether the Hibernate 5.0 release schedule can align 
with the WildFly 10 schedule, so that we can do the work.
