At a lot of companies, there are still full teams of people slinging t-sql or pl/SQL all day long to support their organization. Not DBAs, just developers who primarily work inside the database system their entire life.
I keep my old SQL Server Anki cards alive for just such a use case. It's been a minute since I had to jump into a 3-digit-LOC SQL script that does some arcane financial processing or what have you, but there's a nice steady niche there in case I ever want to throw my hat back into the ring.
