You misunderstand how the "document replacement" in y-prosemirror works. It's like arguing that React is bad because it performs a complete document replacement on every change. The diffing part makes it fast.

That said, it's not without problems - I acknowledge that. But it's not as bad as you make it sound. You didn't list one concrete case when you had issues with it.

I'm very happy that Nick and I finally found funding to make a rewrite happen. It really did take 6 years to make this happen, because it's hard to find funding for open source projects.

Just tying up loose ends here, in this other comment I suggest that Kevin and I are not on the same page about the point I was making in the article: https://news.ycombinator.com/item?id=47422455

I will additionally note that I'm not making any point about performance in this comment either, though. "Perform" in this context is not about 60fps, it's about whether, like, plugins work.
