global package directory with symlinks to local node_modules

[happysalada]

Hey, thank you for the awesome package manager!
I have a suggestion, but I would like to check your thoughts on the idea before making a full blown RFC.

The idea would be to have a global folder containing all the packages, and the node_modules folder on different projects would only contain symlinks to the global directory.
pnpm does this by default, and in a more general sense, this is the key idea behind the nix package manager.
The one problem it solves is having huge node_modules directories when you are doing several projects and having to refetch packages that you already have on your system.
I completely understand that this is quite an undertaking, but it would be an awesome feature to have.

If you like this, I'm happy to provide more details and start an RFC.
