I think most people don't care how much of systemd is pid 1, there are components like udev that systemd is assimilating, we just want choice, I happen to like modern daemontools-like init systems a lot, but I use various init systems depending on what I want, and that's great IMO. However, read this:
Unless the systemd-haters prepare another kdbus userspace until then this will effectively also mean that we will not support non-systemd systems with udev anymore starting at that point. Gentoo folks, this is your wakeup call.
The factually incorrect statements stem from such messages from lead developers, they've stated that in the future systemd will be sort of "merged" with linux, and that's no good. We know because we've been using great OSs and this is clearly a regression.
