I didn't put my admittedly sarcastic attitude about this topic very clearly.

As of ten years ago, most change management was seat-of-the-pants, ignorant of any theory, relying on adhoc rules-of-thumb or so-called "best practices", a euphemism for basically nothing, "applied" by a selection of mostly mediocre people from various disciplines. Being that way, they were mostly unaware of database theory. I suspect nothing about that has changed. If so, change management "practice" now lags a further ten years behind.

The great value of theory is to make precise predictions. A layman might reasonably think that ought to be the main purpose of change management. I think you are confusing practice with application.
