The thing is, information on how to do it in a safe and healthy way is available, sometimes even from your national food agency.
The problem is, I think, that people do not follow the guidelines of the food agencies anyway. If you follow the guidelines but on a vegan diet, making sure to supplement b12, you won't have to do any planning. A healthy dietary pattern looks the same if you don't eat meat. People most often just have to make sure they get enough calories.
