I can see the periodic rotations used as a way to keep up the operational experience. This is indeed a valid reason, although it needs to be weighted against the increased risk of compromise due to the rotation procedure itself.

I'm just saying that rotating the key just in case someone compromised it is not a great idea. Doubly so if it's done infrequently enough for the operational experience to atrophy between rotations.

And yeah, I fully agree that anything surrounding the DNSSEC operations is a burning trash fire. It doesn't have to be this way, but it is.
