"Are you sure?" prompt after assigning all skill/attribute point --- uh no thanks.  Why not just click the ability once you're ready to make your decision?  If respecs weren't so easy I might change my mind about this but it's fine in it's current state imho.  I don't want to have to do 4 extra dialogue boxes every level up.
Yeah, I was thinking more of the new player experience.  Free respecs are available once the Lady of War arc is done, but that isn't for some time.  I guess the early game is forgiving enough to allow for some mistakes along the way.
I've been using my spare time looking into modding some of this stuff myself, but a lot of it isn't as intuitive as I thought.  There're plenty of guides, but none of them seems to address a lot of requests from either QoL post.
