I did.
Oblivion and Morrowind had Attribrutes.
I was using Pathfinder as an example of how to properly incoporate Perks.
Skyrim got rid of Attribtues and Skills and instead went for Perks. I feel that Perks were the wrong way to go.
In Pathfinder, yes I am going to mention it, they have Perks they are called Feats. Feats are like special abilities you get as you level up, and they act as Perks. They determine the strength and specials you can do with your skills.
If TES wants Perks. I think the better way to approach it is allow us to customize our attribrutes and skills, further than just Health, Magicka, and Stamina. And add Perks as extra specials for the stuff we can do.
