With PBR being rolled out, Linden Homes should be updated:
* To use PBR textures
* Have pre-placed reflection probes for each house
* Region and parcel default environment presets updated with PBR compatible settings.
* Reflection probes setup for public spaces (if needed)
Having Linden Homes updated with PBR features would show off the capabilities of PBR, as well as give people an example of how Reflection Probes should be setup in variety of house configurations.
