When working with formatted text content like in Google Docs / Zoho Writer: moving a list item down or adding a new column or any table/list operation is essentially a tree manipulation op.
Concurrent conflicts in such cases are notoriously hard to converge without contextual special handling [1]. Does this implementation generalize a solution for such use-cases?
I guess it should be possible to combine a list(or string) CRDT for leaf nodes (i.e text blocks) and use this tree CRDT for structural nodes (lists & tables).
But that will make augmenting every op with two-dimensional address (parent-id, index_offset_into_that_parent)
