I see the difference as, if implemented as a C library that keep a buffer
and synchronize with emacs, then this synchronization *must* be
absolutely correct, otherwise it mess up any operation on the buffer.
However if the CRDT is kept on the emacs buffer itself, it’s much
more tolerant to untracked text in the buffer.
