The Yarn package manager has an option called enableGlobalCache which makes yarn store its package cache in a global folder. Yarn's normal mode is to store its cache in <cacheFolder> which is in the project folder by default (.yarn/cache).
What is the reason to use enableGlobalCache? Is it just for saving disk space? Are there any downsides?
I am asking because I'm puzzled — if it has a use case and there are no downsides, then why is it not the default?
