If your process is bothering you, change your process - it's in your control. Write a new bullet point: "doc-only updates can skip review and CI". When you make a doc-only update, you click the "skip checks and merge anyway" button. Some people are so preoccupied with making sure things can only be done a certain way, they don't stop to think about whether it's the right way.

Of course someone will object to doc-only updates not getting review. That person is now on the hook for reviewing all doc updates after you merge them. It's the exact same thing you were doing before - they only objected when it got formalised.
