Maybe it's just me, but if I were to start depending on other's UI frameworks again, then stability would be the first thing I'd look for, and with that I'd probably want to stay as far away from anything "agent" as I can.
Edit: I just realized that that "framework" is the same ArrowJS that used to be a "library" and the selling point was how small it was, and how it wasn't a framework (https://web.archive.org/web/20230609020338/https://www.arrow...), incredibly funny they pivoted into making it a fully fledged framework after all.
