   Two more commits, both local fixes found after the last review:
   
   - `5af2cd2a3f`: the pending removal features point at #16691; #16745 was 
closed as its duplicate.
   - `d5774b0d45`: fixes #16748 (`is empty` / `is not empty` on an association 
that shares a join table and a key column saw the rows of the other one). 
Hibernate 7 puts the restriction of a many-to-many collection on the join to 
the element, which the `select 1` of its `exists` subquery never renders; 
`size()` applies it. `RestrictedCollectionSqmTranslatorFactory`, registered as 
`hibernate.query.sqm.translator` unless the application sets one, translates 
`is [not] empty` as `size(...) = 0 / > 0` for a restricted many-to-many 
collection only; a dialect with its own translator (Sybase) keeps it. 
Single-table update and delete are covered, multi-table ones are not 
(documented). Covered for HQL, criteria, negation, update, both shared shapes, 
and a restricted one-to-many that keeps Hibernate's translation. Full core 
suite (with the Db2 branch on top): 4275 tests, the only 3 failures the Oracle 
container not starting locally.
   
   The Hibernate bug itself is drafted for the Hibernate Jira.
