--- Comment #1 from Brooks Davis <brooks at FreeBSD.org> ---
The layout of struct utmpx is part of the libc ABI and the format of files
stored on disk so this can't just be changed.  The effort required to make this
change properly would be substantial.  At a minimum, libc compatibility shims
would be required with new symbol versions and a mechanism to handle there
change in the format of /var/run/utx.active, /var/log/utx.lastlogin, and
/var/log/utx.log.  See getutxent(3) for one set of effected interfaces.  A
number of syscalls use MAXLOGNAME and might need to be altered as well.
