That's fair, I guess when I hear "radical overhaul" when discussing PKMs I immediately start worrying about the overload and burnout that doomed my first attempts at Obsidian (see my sibling comment), whereas right now I have a system that works very well for me, especially now that I can just ask Claude to scan the whole directory if I want to ask it questions. But if you do come up with some new blue-sky vision for PKMs, I'd love to at least take a look.
