You only need to make the app once before running it on a million computers. So it's more like greasy flavor development, then de-greasinating the recipe before going into mass production. It's not a big efficiency impact overall, it's more about how you like to spend your flavor development time.
1. Make extra greasy pizza. Nauseating-level of grease.
2. Put pizza through De-Greasinator 5000.
Sounds efficient.
