There is a difference between multiple collection roles that are "parallel" to each other, and when they are in "series".

Aren't those two statements contradictory? First you say: We do it like Hibernate, one collection per query in an OUTER JOIN, no product.

Then you say "Hibernate doesn't allow several collections in a query, thats what we are adding".
