v364 is the current version of OHOL, so I assume all those things would be true by default, if server population is high enough. 

On the plus side, it is pretty easy to switch off race restrictions and homelands, server-side.   Multiracial families would be harder, since I think that would require re-writing code.   Not sure about posse mechanics.

If Eve spawns are the same as vanilla, families will probably end up pretty spread out over time.   This game really isn't optimized for low pop servers. 

Anyone remember One City server?   You always spawned into the same spot and always as an Eve.   It was a building-focused custom server for people who wanted to make impressive structures and cities in a static world.   Pretty cool concept.
