No it isn't. You'd always want to create a feature branch so that you can PR the fix - it's a change going into master, it should go through the normal change-going-into-master review flow. And you'd always have to run some command to indicate that this was the branch where you wanted to undo what you'd done to master. That the command is called "revert" is a little weird, but it's no more paperwork than any other command would be.
