hey @QMalcolm , i was reviewing this dbt-adapters PR and this core pr -- am i correct in thinking that the following needs to be added to the behavior flag doc:

• the require_batched_execution_for_custom_microbatch_strategy flag defaults to False, which will raise a deprecation warning. Set it to True to allow custom microbatch strategies (like get_incremental_microbatch_sql) to use batched execution.
