Would it also be possible to use the files from node_modules?

Hey there, I'm wondering why we are downloading things from npm "again".

Especially in the case of using the usePackageJSON option, after installing the dependencies for a project, all those dependencies are already available in the local file system.

What would it take to just use those files?
Or is there a good reason not to do that?

Meanwhile we switched to copying files from node modules, which is of course way faster and more reliable.
For that we use some custom field in package.json that points to the file in the the node_modules/package folder, which we nerd to copy, since we need to pick the correct UMD build.
We also have some handling for development mode, where we copy source maps of that file if available and look for unminified/development version of a file and copy that one instead.
