Earlier quoted context omitted.
SMF runs circles around systemd. I used it recently, and realized it is what systemd is trying to clone. It was kind of like learning Unix after coming from a DOS background. If FreeBSD switches to systemd, I'll stick with OpenBSD. OpenBSD is as likely to switch as they are to rewrite the kernel in rust and go.
FreeBSD will never, ever adopt systemd. That I am certain of. Even if the license wasn't an issue, and you could easily yank out all the non portable Linux code, and adopt it into BSD, the code quality, and the engineering of it would not meet BSD standards for adoption. TrueOS just started using OpenRC and seem happy with it so far.
I suggested to them back in January 2017 that since OpenRC has s6 integration, they might do well to add s6 to that to gain full service management. I never received a reply. I haven't heard that Laurent Bercot was contacted, either.

I personally use the nosh system and service managers on FreeBSD and TrueOS, of course. I just wrote up a more detailed account of how I used them on TrueOS to run the PC-BSD desktop login and chooser utility under proper service management, and to improve several parts of that subsystem.
