Terrain collider and 1.0

Will there be authoring for ECS 1.0 TerrainCollider? Is there already a way to use Unity Terrain with ECS?
I know that there is a TerrainCollider, but I haven't found any information on how best to use it with the current terrain.

 

I wanted to try to make a Unity Terrain and an ECS Bases no-kinematic Character Controller. I did not want to create a custom terrain system for a larger terrain. For testing I used meshes, but I also came across the problem that the Character bounced on mesh edges.

 

It's been a bit longer than a week, and wondered what info might've been gleaned since?

 

I still use the methode discussed here : https://forum.unity.com/threads/using-unity-terrain-with-dots-workflow.755105/

Still works for entities 0.50.X. But the rendered terrain is an non-ECS gameobject (Convert and Inject)
