Yes, I agree. Nevertheless, the couple of times I saw this the message itself was useless. Once, the keyboard didn't work and the other was unplugged, but plugging it didn't work until turning off and on...

Well, this is not a message seen in a piece of software being debugged or modified... does anybody remember that useless message "Keyboard not found. Press F1 to continue." that old BIOS (AMI, I believe) used to show when they could not detect a keyboard? A long time ago, but I've seen them in old 386's and 486's. I know, I know, that was last century. ;)
