No, of course other things are important.

But if you measure only ancillary things, that's a pretty bad measure.

I don't expect every one of my team members to understand the entire build system, testing setup, logging system. That's a waste of their time. They should know some, and perhaps one of the areas in depth.

My point is: Those things aren't ancillary. They aren't a waste of time. Good developers can figure out how to use logs to debug issues. They can figure out how to fix the build and deployment system when it's broken. They can figure out how to set up testing environments. If not them, then who? Managers look for people who are self sufficient. All of this stuff is a necessary and important part of the job.
