If I am put my 5 cents (inflation).  My personal default is (PERSIST, MERGE, REFRESH) and in the circumstance that I need to put a DELETE then I would if necessary.  I assume beginner Seam developers would absolutely freak if they saw a detached entity exceptions when they first use Seam's reveng.

2) What default do you think we should use for reveng, ALL or NONE (or something else ?)

none

What about PERSIST? I really like to be able to do this.

Child c1 = new Child();
Child c2 = new Child();
Parent p = new Parent();
p.addChild(c1);
p.addChild(c2);
em.persist(p);

With none, you have to go through and do persists all over the place...and in a real application, that top level object typically has 10+ relationships, esp if lookup tables are used.
