Use-cases of subscribers for integration extension

The subscribers don't seem to have any context. Because of that I'm unsure how and why one would use subscribers besides the most basic logging to the console. https://docs.vuestorefront.io/sdk/advanced/extending-module#subscribers Can this be elaborated?

Extending a Module

In most cases, a module exports the base set of communication methods and utilities.

It looks like you can pass in a generic params

subscribers: {
    "*_before": (params: any) => {
      console.log(`Before each * method do something`, params);
    },
    "*_after": () => {
      console.log(`After each * method do something`);
    }
  }

subscribers: {
    "*_before": (params: any) => {
      console.log(`Before each * method do something`, params);
    },
    "*_after": () => {
      console.log(`After each * method do something`);
    }
  }

Yeah, you're right and as mentioned in the docs it's good to use them for logging or collecting analytics data. Subscribers don't affect the request/response since they are not blocking the request, but simply run in parallel with the request using pub-sub pattern.
