OK, let's discuss this.  My first comment is that when you have custom 
programs like this, the author has to think about everything an admin 
might ever want.  What if the admin wants something the author didn't 
think about?

Second is that you are using different tools from other logs such as 
apache, ftp, mail and any other application that writes a log.

Third, if the logs were ascii, the bells and whistles in the link above 
could be accomplished with a bash script fairly easily.

About the only really sensible argument is that binary logs use less 
disk space.  In the days of TB drives, even that isn't a big deal.

To me the whole systemd philosophy moves away from user knows best to 
developer knows best.  That's just like MS and Apple.  The difference of 
course is that systemd *is* open source and we don't have to use it.

P.S.  I never did like wtmp, btmp, utmp for pretty much the same reasons 
as above.
