I found a weird tag: cpupower-command. I looked at whether there was an already existing cpupower tag and there was not. There is no good reason why cpupower-command should not be cpupower. I changed the only question's tag to my newly created cpupower.
I think this command isn’t worth an own tag at all – a quick search showed just a bunch of questions mentioning the command, not more.
I vote to delete the tag(s).
