* `splice-subqueries` optimization is not limited by any type of operation within the
subquery any more. It can now be applied on every subquery and will be by default.
However they may be a performance impact on some queries where splice-subqueries
are not as performant as non-spliced subqueries. This is due to internal memory
management right now and will be addressed in future versions. Spliced subqueries
can be less performant if the query around the subquery is complex and requires
lots of variables, or variables with large content, but the subquery itself
does not require a lot of variables and produces many intermediate results
s.t. good batching within the query does not pay off against memory overhead.

* Supervision to clean up zombie servers after 24h, if no
responsibility for shards.
