I watched the presentation, but I'm getting the impression that you're still using a hierarchical XML-like structure for the document, which sounds like it still cannot merge or split nodes (without recreating the content after the merge or split point). Will issues like https://github.com/yjs/y-prosemirror/issues/205 be addressed by this? (Which not only breaks ProseMirror's position mapping, but also your own, and which I consider a serious enough bug that recommending y-prosemirror for anything feels unserious.)
