I made this in large part because it can be so difficult to convince a non-technical stakeholder of the importance of some security aspects. With the report, this gets much easier.
Further, though this isn't really explained well, is that there are some optional security elements like http->https redirection, HSTS that are just blips on the SSLLabs report that I think should be of more importance.
The Simple report was meant to be a sort of executive summary, not a deep dive.
Like it or not, many times non-technical people are in charge of approving technical budgets and requirements.
