It is still useful. In particular, kernel is now very verbose, so important messages during bootup scroll away. It is way bigger deal when you can no longer get to them using shift-pageup. fsck is rather verbose, too, and there's no easy way to run that under X terminal... and yes, that makes scrollback very useful, too. So, I believe we'll need to fix this. I guess I could do it. I also guess I'll not have to, because SuSE or RedHat will want to fix it. Anyway, this really should not be merged into stable.
