 The caching capabilities of the action are limited for the simplest builds and can be ineffective in the real world

 If there are several builds on the same repo it might make sense to create a cache in one build and use it in the
 others. The action [actions/cache/restore](https://github.com/marketplace/actions/cache-restore)
