I'd be concerned about this: the OOM killer applies heuristics only and can never guarantee to kill the process that is responsible for low-memory conditions, so if OOM runs at all, system robustness is no longer guaranteed. This may lead to unpredictable and nasty behaviours when the platform is no longer freshly installed, extra packages and daemons have been added etc....

Relying on the OOM killer behaviour for correct operation of the system feels unsafe to me.
