I'm sure this has been brought up before. Sometimes I want colonists or animals to be forbidden from accessing certain things, but I don't want to create a whole new 'inverse' allowed area. For example I don't want the whole colony to have access to my drug lab, but 'everything but the drug lab' isn't a good allowed area to have to make. I want to save up pemmican for a long caravan journey and don't want everyone eating out of the pemmican pantry. I want to stop my yorkshire terriers from going in the cooler and drinking all the beer. Etc. And sometimes I want to mix and match, e.g. some people can go in the beer cooler but not the drug lab. Making a new allowed area for each case is a lot of work, not to mention very counterintuitive.
That would be nice. You can forbid doors but not for specific colonists.
