Good idea with "soft dependencies". You'd also need to make the go.mod RequireSpec version argument [1] optional so it can be overridden by the module group.

They look interesting, but appear to exist for a different purpose. Maybe workspaces with a bunch of replace directives & some cli tooling could emulate a system like what is described here.
