TTF is a CRDT-like approach. They both maintain an extra data structure including tombstones. And TTF-operations are only applied on the designed data structure. To be applied on the document visible to users, TTF-operations need to be translated like CRDT. Your solution is to combine GOTO with TTF. Actually, it is a combination of OT and CRDT.
