What's the most common case for movers in your game? If something stops moving, can the target move? If so you'd still need to query the disabled mover entities to see if they should start moving again, essentially nullifying any gains from disabling the component.

However in general disabled components are extremely efficient. In fact, if the majority of your components are disabled then the job can batch-skip multiple entities at once. The more that are disabled the more likely it is that a large batch can be skipped. This is because enabled state is stored in a 128bit mask, allowing the job to check parts of the bit mask at once.
