The same thing can be said about other skills though. I'm actually all for having them separated but I also want more other skills. Having absolutely everything from astronomy to botany to mathematics and everything in between being covered in one skill just does not feel right to me. But splitting 4 skills (scouting, spot hidden, sleight of hand, sneaking) which could just as well be one skill called "thievery" is apparently ok. Yes I'm of course generalizing and I don't think that should be done but I think you get my point.A person that has hid himself is not sneaking anywhere, he has hid himself and then he stays hidden hoping that no one finds him. Scouting can be seen as some sort of danger sense, you can detect if someone is sneaking upon you, perhaps to get near so they can pickpocket you.
By separate those skills, we can have someone who is an expert detecting secret doors, hidden treasures or clues, but isn't necessary good at avoiding animals or monsters sneaking up on you in the wilderness and vice versa.
We don't have the full rules so we have to wait for that before we know. My description is based on what little Tomas have mentioned in interviews and how earlier editions have handled this.
The same can be said about persuasion and survival at least.
And also I want a skill for shields but that also requires some more adjustments to the combat system like having an extra action for your second hand but I've covered that in the swedish thread.
