-- [ ] 2.3 Remove the now-dead `ClusterConfig` port defaulting in `myconf.c` and `config_repl.c`
+- [x] 2.3 Remove the now-dead `ClusterConfig` port defaulting in `myconf.c` and `config_repl.c`
   - Delete the `SET_DEFAULT_IF_UNSET(c->port, 0, 9990)` call in `myconf.c`
   - Delete the equivalent `SET_DEFAULT_IF_UNSET(c->port, 0, 9990)` call in `config_repl.c`
   - Observable: `myconf.c` and `config_repl.c` compile without referencing `cluster_config_t`'s `port` member
