I continue to work on my Salesforce Developer journey. And during my Build a Bear-Tracking App with Lightning Web Components trailhead, I figure out that: we may include one record to another with compact layout.

As well as we have ability to edit that another record being on the same page. Which real use cases I see? For example, being in some role and working with the child record. I need to change something on the Parent record on the regular basis. And that thing will save a lot of time to be in focus. Maybe it will help on lead generation process, where we gathering information about client. And in the beginning it is not correct.
