Unity Terrain Team

This might be a bit cheeky, but I'm wondering what the new unity terrain team are working on... It's tricky at the moment for making environments. i.e. with HDRP still under development many assets simply aren't supporting it and the standard tools are limited.

e.g. are unity working on their own terrain painting tool - more than 8 materials/pbr/height blending/brush editing in viewport/terrain blending/etc...

and what about all the other features - vegetation/water/skies/etc etc etc - I'm not wanting to take away from the asset makers (and some the great tools out there) - but curious to know where Unity in-house dev' is going for environments.

Is there anywhere that lists a terrain roadmap or something similar - if not, could there be?
