I have some Hanwag Hallux boots which are unlined. I wouldn't recommend them outside of Summer though. They are nubuck and made of quite a few pieces (they are very similar in design to Lowa Renegades). They get sodden and leak in a day when walking in wet weather, especially wet grass, even thought they've been thoroughly and repeatedly waxed with quality wax.
So if I were getting unlined boots I'd make sure they were full-grain leather and made of a single piece, or close to it. If Altberg did unlined, I'd consider them. I personally do not think nubuck every gets as waterproof as fullgrain, no matter what you do it it, because the layer they remove to make it Nubuck is the layer that is most naturally waterproof, close-textured and dense. I don't get the logic of using nubuck in walking boots TBH.
As for goretex boots not breathing and not drying out well, I agree with the former but the latter seems almost irrelevasnt - as far as I can tell no boots dry out in UK wet conditions anyway - that takes indoor drying.. My unlined boots certainly do not dry out to a usefull level on backpacking trips. Maybe they would if it's hot and sunny and get get dunked just once crossing a stream or something, but not on the soggy Welsh or Dartmoor walks I do. Personally I'm converted to Goretex
