I'm not contradicting this but offering a contrast, I like Hermes because it simultaneously lowers barrier of entry and shows you what possibilities are unlocked by agents. I don't think I would have the time, interest or creativity to jump into the deep end by either extending an existing harness or rolling my own from the start. This also isn't an argument for doing just that, I might do so in the future, but critically only after Hermes has shown me what's possible and my preferences are developed.
