Let's provide a possibility for QMP-based orchestrators to get an error like with outgoing migration. For hmp_migrate_incoming(), let's enable the new behavior: HMP is not and ABI, it's mostly intended to use by developer and it makes sense not to stop the process. For x-exit-preconfig, let's keep the old behavior: - it's called from init(), so here we want to keep current behavior by default - it does exit on error by itself as well So, if we want to change the behavior of x-exit-preconfig, it should be another patch.
