Objections? Hmmm ... AFAICR the '@' symbols can be used to set the kill character and the '#' can be used to set the erase character. But for a virtual console terminal those characters those are normally not used. Only connections at dialin as well connections over some serial lines with hardware/software line routers/terminal servers between this could be problem. On big irons such serial lines are used even in the present days. Maybe it would be worth to introduce an further option to support access domains in user names ... or the other way around to support '@' and '#' as special characters used for software escapes on oldish connection lines.
