``` static int optimistic_data_enabled(void) { const or_options_t *options = get_options(); if (options->OptimisticData < 0) { /* XXX023 consider having auto default to 1 rather than 0 before * the 0.2.3 branch goes stable. See bug 3617. -RD */ const int32_t enabled = networkstatus_get_param(NULL, "UseOptimisticData", 0, 0, 1); return (int)enabled; } return options->OptimisticData; } ``` Has anybody tested it? Should we try turning it on in the consensus to see what breaks? Do any applications use it?
