Well, the Raspian people do, and they have apparently already added the tool to so that it is updated automatically.
Edit: Ah, I see what you mean. I was not wondering why it was in a separate tool, but why they recommended on the website to update the eeprom automatically (somewhat hidden) but did not include it in the image, which they subsequently have.
A good thing, too. might as well update documentation, but the no harm done I trying to install something that is already installed.
So @wiedehopf was right after all
