Yes it is. But it is nice to have this generic standardized mechanism we can build upon. Setting it results in reproducible behaviour (timestamp, random output, machine-, user-, hostname is replaced).

Like i have said in the other mail, yes and no. I will add uname(2), but keep uname(1), too. Better that is.
