They have been supporting Unchained classes, like the Monk and the Summoner, in recent publications. One thing that would have been nice to see more is the Magic Item Scaling rule.
Here's the thing: any magic item of this kind can be treated as a "new kind". You would have gotten "static items" and then "scaling items". Furthermore, I feel like scaling items are a tad bit more appealing for players and GMs alike, because they just need to obtain an item and "have it grow on them".
