While that sounds like a clever trick that Apple could use, they really want to minimize production costs and maximize utility for consumers. Their profit margin comes from a share of that surplus utility. I suppose it can help hide price increases of the next higher configurations, such as when the base configuration of the MacBook Pro decreased from 256GB to 128GB between 2016 and 2017, with the list price for 256GB configurations increasing by a couple hundred dollars. However, Apple has also gone as far as developing an entirely new filesystem to decrease storage use.
