The main issue is that systemd-sysv conflicts with sysvinit-core, while
the systemd package doesn't. If you do the first install of systemd with
systemd-sysv, this doesn't only change the default, but forces the
removal of the whole sysvinit implementation. This can be compared to a
kernel package install that forces the removal of all previously
installed kernels before you can boot to the new one.
So the systemd-sysv route has the clear technical disadvantage that it
does not support parallel installation of sysvinit and systemd. I think
the ability to easily switch back to sysvinit for troubleshooting if you
encounter issues does have some value. Of course, it would be possible
to switch /sbin/init while both are installed.
