Gaekub, the "willing" text is in the rules, and not replicated per spell. Your fix would work to keep the current logic. ...
Maybe I'm misunderstanding you, but the willing text is both in spells and in the rules (to explain what "willing" means"). The target line of teleport is "you and touched objects or other touched willing creatures". Spells that require a willing target specify that, and I'm suggesting moving the unconscious caveat to the spells instead of saying in the rules "unconscious counts as willing".
I am intending to stick to the current logic for the "willing target" mechanic. That's the function I prefer.
If the goal is to prevent the bad guy from teleporting you without first shoving your body into an extradimensional kidnapping sack, then have rules to that effect. Spell out specifically what happens when. If the player has to actively say "willing for this, not for that", then you end up with goofy situations like "communicating with an unconscious person via prearranged code" and "intimidating unconscious person with scary spell names" and other nonsense.
I do not want to prevent a bad guy from teleporting away with an unconscious person. I agree that making decisions about whether or not you are willing or whether or not you would like to make a save while unconscious would lead to weird situations (and is just weird in general in my opinion). That's why I suggested using the harmless keyword to differentiate between spells an unconscious person will save against and those they will not.
