> **(medium)** With FLUSH_TRUE (default FlushModeType.AUTO) this now flushes
> before every query as soon as anything in the context is dirty, and the
> `flush == FLUSH_TRUE` addition at line 1033 also overrides the IgnoreChanges
> setting. That defeats the access-path optimization and can be a real perf
> regression in write-heavy transactions - can the broadened check be limited
> to types related to the query access path, or guarded by a compatibility flag?
