No, I haven't seen a corrupt "unparceable" document. It's more issues around documents that don't comply with the schema.

Say for example you have a <figure> node that can contain a single optional <caption>. If two users concurrently add a caption, then merge their changes, the Yjs document will contain both. It has no concept of what the valid structure is. When this is loaded into the ProseMirror the second caption will be dropped.

Hmm hadn't thought about that. Yeah Yjs should use more granular steps instead of just replacing the whole doc each time remote update is received.
