This is a non-issue of a story. Normal cyclical review of doctrine.
I feel the article author was trying to show that this piece of doctrine can be applied in a large variety of scenarios, which is the point, no one has time to write, read, and train for all the different type of insurgency, so a single source document makes a lot of sense.
Right on page four, it has a pictorial of COIN being the gap between peace support (something like Cyprus) and major combat operations (Ukraine) with overlap. Something like Haiti would fall under a peace support / COIN overlap, something like 2019 Ukraine the COIN/War overlap. This publication needs to cover ALL of that.
The document came out of some hard earned lessons in Afghanistan, but all doctrine should be reviewed periodically regardless.
