Im definitely going to look into this and get this added for 3.0
That said we are making plans for our next move after 3.0. Currently you can come to our Discord and share your ideas for a new mod called "Extinction" that will be a more traditional but definitely more hardcore style mod like Ravenhearst. The idea behind this mod, is almost NO craftable recipes, scavenger heavy, walk only traditional zombies with headshots only.
Think Walking Dead where looting is VERY important. Zombies will do minimal block damage but will be ALL over. There have been dozens of great ideas already thrown around in the discord so if you have an idea on how to make a real world based survival version of 7 Days without mutated zombies and with realistic building and crafting head there and add your ideas. There are so many great ideas already posted there.
