The problem is that some projects started depending on systemd behaviour now and the transition hasn't been smooth at all in Debian even if you want to stay with sysvinit. I'm still on sysvinit with systemd-shim, and things started to break in KDE already, mostly related to authentication (can't mount USB devices, can't manage VPN connections, etc.). In the end I'm afraid Debian users might not have much choice: either use systemd as PID1, or use another distribution (like Gentoo, etc.) that work without systemd.
