Hi! In the following article: https://blogs.technet.microsoft.com/stefan_gossner/2016/08/09/psconfig-improved-error-reporting/ Stefan shows how MS is improving the PSConfig, in order to throw the root cause of the error when the PSConfig fails for any reason.
I think that it is an important feature, because would be easy to find a problem when it happens in our SharePoint farms.
Happy SharePoint!
