Not every operating system needs to be a cathedral. Some OSes are not trying to replace Windows, macOS, Android, or a full Linux desktop. They have one job, a narrow audience, and very little interest in bothering you once they boot.

“Tiny” here means different things depending on the project. Sometimes it is a literal install size measured in megabytes. Sometimes it is a tiny hardware footprint that runs happily on something you would otherwise throw away. And sometimes it is a tiny ambition in the best sense — a piece of software that decided early on exactly what it would never try to be.

A couple of these don’t complain so much as they expect you to know what you’re doing instead. That’s its own kind of low-key.
