Is that still true. I thought we addresses this at least for hierarchies in https://hibernate.atlassian.net/browse/HHH-7484. See also MetadataSources#indexClass. Nothing stops us (for good or bad) to for 
example transparently add all superclasses of a specified class.

What is the exact issue and what do you mean with "tests using not-completed orm.xml "?

I guess I need to see first which tests are failing to better understand the problem.
