Could you point to a specific example please? Or screenshot if those are apps. I'm curious about trying some accordion pattern that people actually _like_.

We're in one right now?
There's nothing much to it, it's just collapsible nested lists. And to be clear, I think most people would be weirded out by a blog post that looked like that. I think making the "flat" view the default one but adding a toggle for a hierarchical view would be the ideal UX for me, but I bet this is a very niche preference and it wouldn't be worth it for a larger audience.
