I basically agree. From what I hear (I don't own SCAG) there was quite a bit of "older-edition hangover" in that book. Things that were assumed to carry over but not stated as much. I'll note that there's nothing in the style guide for FR (freely available on DMs Guild) that says it exists, and it covers quite a bit about everyone being religious/active gods. And there are strong notes in the general style guide not to assume that anything from previous editions still holds unless it's said in a first-party publication.
