Yeah, I follow, and I generally agree with that reasoning for a fresh
install of a fully systemd distro.

In our case, we needed to handle things like transition from sysvinit
scripts to native units, tracking whether they were enabled as sysvinit
and ensuring that state information was mapped over to the native unit
state too (as this was an upgrade, the "systemctl preset" was never run
anyway).

But, yeah, longer term I agree with the rationale.
