I would expect that these fluctuations match the actual changes in BGP.

This could be interesting research, provided you have detailed enough history of both BGP and VRPs.

My hypothesis would be that a longitudinal analysis would show that it's related to RPKI uptake, especially w.r.t. validation which gives a strong incentive to fix ROAs if they disagree with your routing intent. So I would expect that the change rate in ROAs increasingly matches changes in BGP, and that possible delays in ROA updates wrt BGP are now getting shorter.
