Fairly against this article. It fails several showstopping ways.
1. Many of these are the sorts of things that a character can already try. Now it's a gate where you can only do these with the appropriate feat.
Another category is "I want to become better at skill (non-magical) use, so no matter my concept you grant me magic". Hey, I want to become better at survival or knowledge(nature), so the solution is to give me a magical spell instead. This hits one of my hot-buttons (I lambasted several spells-replacing-skills in the recent spells UA feedback).
2. These are leveraging the "half-feat" mechanism to only give out a smaller benefit, but really feats are so scarce that these become rather wimpy. Sure, if you really want that ability score AND you have planned (probably from character creation) that a +1 will bump you to the next modifier, it's not bad. But otherwise it's trying to have lesser feats, which works better in a system with more frequent feats.
The corollary is that if you are now high levels and have already maxed you ability score can now afford to take second choice feats, there's a whole category of ones you won't take because you're already capped.
Sorry, dislike this whole article.
