Exactly, but it goes further than that. The mentality never made sense since the term NoSQL never made sense to start. It's amazing how many people use a term that just originated from a meeting to talk about alternative databases. How we keep using it, although it's practically impossible to say what NoSQL is. Depending on whom you ask that term means different things. This is a very good introduction to the term: https://www.youtube.com/watch?v=qI_g07C_Q5I

Graph databases are considered 'NoSQL' yet they have relations and transactions. Schemaless is often also one of the properties give to NoSQL, but it's also a bit strange to consider that a NoSQL attribute. Some traditional databases offer schemaless options and databases like Cassandra has schema yet is considered NoSQL. I work at Fauna which has relations, stronger consistency than many traditional databases. It is schemaless at this point but that might change in the future. Since it doesn't offer SQL it's thrown into the NoSQL bucket with the assumptions that come along with it.

None of these one-liners in computer science make sense IMHO and we listen way too often to colleagues who use them. Similarly "Use SQL for enforced schema" might be accurate in many cases but in essence it depends on your situation, and we need to do research about what we use instead of following one-liners ;)
