The first rule of data modelling is that you should model only what you care about. A good model allows you to store and retrieve what you need to meet your requirements.

Maybe you care about all the events that have ever happened on your incredible journey to reach a list of the customers you have today.

Or maybe it would be sufficient to have been mutating a customers table all along. If that is sufficient, then it would be faster and more straightforward to have done so.
