Thoughts on skills in OSR systems and WWN

I know a lot of players have strong opinions on skills/feats in OSR systems, afaik normally towards the negative side. But even then, I often see Worlds Without Number (WWN) as one of the most recommended system around, and that system has skills/feats.

So, I'm just curious on why is that? Is it because of the way they are implemented? Or maybe people are recommending it more for the GM tools and guidance instead of the system itself? What do you all think about the skills/feats implementation on WWN? Any other opinions on skills/feats systems in OSR games in general?
