State of git workspaces?

[Nkmol]

This might be a continuation on the topic of npm/npm#2974, where the main stance was to not support monorepos as the focus was to not add more features/complexity at that time. With the introduction of workspaces, I have the feeling this stance has slightly changed.

For unpublished packages, we already have the options to install them through a remote URL: npm install <git remote url>. However, this method does not work when the repository is a monorepo where no root-project package.json exists, currently resulting in the following error:

npm ERR! enoent ENOENT: no such file or directory, open '/Users//.npm/_cacache/tmp/git-cloneThbqCx/package.json'

To extend the work of workspaces, it would be great if we could integrate workspace in the URL protocol, using the top-level workspace package.json to resolve the workspace name. Seeing it has been discussed before, I do wonder what the current opinions are about this and if this is something that does fit with NPM's philosophy nowadays.

As a reference, Yarn currently supports this through a URL fragment value of workspace=<name>
