The warning was added for a reason, because there was discussion about some people writing extra characters in there, which might cause issues down the line if we refactor the code in future. > After all these years, I think > the chances of fundamental sysrq changes are pretty small, Actualy it is not that long since the underscore mode was added... > but I still don't see why we would take the warning out? Exactly. Thank you.
