World Partition only reserved in local play?

I created my world with WP, a large map of 4033x4033, it’s great I have superb performance in Standalone. I used the same map in multiplayer, it’s slow as hell. If I go outside of my character I see the whole map.

My question, is World Partition is plan for multiplayer?

I also discovered that WorldPartition load far proxy, like a cross even in standalone mode.
