This sounds a lot like what they did to skills on 4e, and I hope a way more flexible aproach to skills in the next edition. I know there are lots of people who just say "use your imagination and roleplay what isn't on the skills", however I really like the skills perform, profession and craft, they give a way to put something on a chacrater background and for it to have a mechanical effect, that is mostly what disappoints me the most of the current system, yeah I'm not 'limited' by the rules to have my character be a good cook, or a good dancer, or whatever, but that no longer means something, no longer I can look into someone's character sheet and guess a background by the skills alone.
Ok, enough ranting, I don't really want to start edition warring, just wanted to exteriorize a feeling. I really like skills as focuses that could even override ability modifier penalties. With them even a very dumb character -but persistant - can beat a natural but unfocussed genius on knowing something. If such a simplistic skill system as described in the link is the default, I hope they at least provide a more customizable (but still functional and not just a reprint of the 3e one, I like it, but it is still far from perfect) alternative in the same book.
