Not just you, I agree with you. 
If you are really riding backcountry I would consider riding a DD casing. Add a CushCore to a DD tire bring a boot and you can likely leave the tube at home. I haven’t carried a tube with me in as long as I can remember but I don’t run tires that require me carrying a tube to compensate. There are trade offs but I guess for me the burly tire that is more resistant to cuts to begin with is a better option than running EXO and a tube in the event the EXO can’t handle the job.
