None, yet but my point was that even if no skill points were needed for professions, new skillpoints wouldn't mystically appear from thin air. You just cannot raise every skill to good level because there isn't enough points to spend. Even character with intelligence 10, skilled trait and educated perk cannot master but few skills.
Well if you take 10 intelligence (even without skilled and educated) you are capable to have your character with 3 tagged skills at high levels (150% each or more), and all other useful skills (science, repair, outdoorsman, fa, doctor in this list) at 101%, so where is the problem?
I think the problem is that you want to make dumb character wiht low IN to get these points to other stats that could make you better in pvp fight and in the same time have skills at same good levels for professions and just using, but that doesnt work that way.
