I'm currently trying to decide between that, Debian/kFreeBSD, and stock Debian with systemd purged and locked/held (so that I can't accidentally install something that requires it).
Why Debian/kFreeBSD? Because systemd is not portable and won't run on the FreeBSD kernel, so Debian/kFreeBSD literally cannot make the switch. I do not care very much about the kernel or about Linux-specific features, so I don't really see much of a downside to it.
(For me one of the core tenets of the Unix philosophy has always been portability. I do not want everyone running on the same kernel, or the same CPU architecture, or the same byte order, or the same word size, or anything. Code should be portable across all of that. Write pure ANSI C if you can, and add POSIX if you must, and if that won't do the trick, then compromise but feel ashamed of it.)
At the moment I'm leaning towards "stock Debian with sysvinit, and further with systemd explicitly blacklisted". Even with all the bullcrap that's been going on, it'll be a while before Debian truly requires systemd for much, and I can hope that they'll just change course before then. I can always switch to one of the other approaches later.
