                I'd prefer to drop HA_MUST_USE_TABLE_CONDITION_PUSHDOWN flag completely. If the user wants to have condition pushdown — she should enable it. In fact, it should be enabled by default. And only disabled as a temporary workaround for some misbehaving engine (that we don't have, at the moment at all).
