Think they'll have even more of a struggle getting people off Trusty 14.04 as that entails jumping into the systemd swamp.
I've been sitting on the fence and weighing options on our next OS as I have until Apr 2019 to complete the move, but one decision I have already made is it will be to a non-systemd OS.
It's been interesting seeing who has gone which way, and the development of non-systemd systems. Still not sure on the best option as yet, though *bsd seems the way to go.
My view on systemd:
One Ring to rule them all,
One Ring to find them,
One Ring to bring them all
and in the darkness bind them
