Unless you are seeking liberation from hunger.
As you say it's what is relevant to liberation that is important, understanding what I take to be me and mine is not self and empty of a separate thingness is what is important. Understanding that the dog and the carrot and the fridge are also not self and empty of a separate thingness goes without saying and I'd have thought was obvious to most people, well maybe not so much in the case of the dog.
I've read posts where people have said that Theravada teaches the emptiness of self only whereas Mahayana teaches the emptiness of phenomena also and they've never made sense to me.
