Some of it can be fixed by automation, but yes it's a problem. The NoSQL trend was partly I think a reaction against the complex feature sets and quirks of SQL databases. But then those features existed for good reasons, and just saying "we do less" isn't really a simplification, it's just ... doing less. MongoDB also distinguishes between concurrent and non-concurrent index builds, requiring you to pick up front. And it's not fully concurrent anyway.
