Your part 1 post was one of the inspirations for that :)

Specifically, it inspired the question: how can one let programmers customize the way edits are processed, to avoid e.g. the "colour" -> "u" anomaly*, without violating CRDT/OTs' strict algebraic requirements? To which the answer is: find a way to get rid of those requirements.

*This is not just common behavior, but also features in a formal specification [1] of how collaborative text-editing algorithms should behave! "[The current text] contains exactly the [characters] that have been inserted, but not deleted."
