I'm not sure that that's the win that you think it is. Linux 10 to 20 years ago was pretty terrible, at least on desktops.
Everyone hates on systemd, but honestly I really think that the complaints are extremely overblown. I've been using systemd based distros since around ~2012, and while I've had many issues with Linux in that time, I can't really say that any of them were caused by systemd. systemd is easy to use, journalctl is nice for looking at logs, and honestly most of the complaints I see about it boil down to "well what if...", what-if's that simply hasn't happened yet.
FreeBSD is cool, but when I run it I do sometimes kind of miss systemd, simply because systemd is easy. I know there was some interest in launchd in the FreeBSD world but I don't know how far that actually got or if it got any traction, but I really wish it would.
