• I'd be willing to implement this feature
• This feature can already be implemented through a plugin

Describe the user story

I believe the best user story are the comments in this issue: yarnpkg/yarn#5428

Describe the solution you'd like

Add support for generating a lockfile for each workspace. It could be enabled via configuration option like lockfilePerWorkspace?

Describe the drawbacks of your solution

As this would be opt-in and follow well known semantics, I'm not sure there are any drawbacks to implementing the feature. One could argue if it should be in the core or implemented as a plugin. I personally don't have a preference of one over the other.

Describe alternatives you've considered

This could be implemented in the existing workspace-tools plugin. I'm unsure if the hooks provided by Yarn would allow for this, though.
