Hey, touching base here. Are you still interested in this RFC?

[alanyinjs]

@zkat Yes I'm still interested! Just trying to come up with an alternative...

In that case let's remove the depth and just pass in the package to start with. That way can still beneficial from showing dependency for a specific package.

The root problem that you're trying to solve for is to filter the view of the dependencies in your project. This is something we very much want as a feature in npm/cli project. However, we don't be able to accomplish this until npm@7 due to some performance, and timeline restrictions. We're definitely going to revisit this once we have the beta of npm@7 out in the publics hands. Thanks so much @alanyinjs for creating this RFC. We'll circle back in Q1 of 2020 on this to get it implemented in npm@7 👍
