(disclaimer: Netlify employee) The big challenge with the cache interface atm is not using Redis (personally, I love Redis). It's that this interface is far from being a straightforward GET/SET/DELETE. Rather, you need to learn the default implementation and all its nuances (for different payload types), and duplicate/transform all the logic.

The division of labor between what the framework does and what the platform developers (or any other developer working on a high-scale/high-availability deployment) need to do, has to be fixed. If this happens - plus better docs - you should be able to "just use" Redis.
