The max unit/faction/province limit determines the amount the resources (CPU, RAM) that the app uses. Raising the unit limit regardless of whether you use the slots or no raises the workload on your machine.

If raising the cap pushes the resources needed to reasonably run the game above the min spec CA won't do it.

You are correct though, the actual changes in the code are relatively easy.
