A distribution isn't a single individual. It consists of different people, developers, maintainers, contributors etc., who are at different levels of acceptance or appreciation of various features of systemd. It isn't as simple as being content with it, or adopting it. In a diverse distribution like Debian there are constant debates about various features of systemd, and that's not only because they haven't decided on systemd yet, but because systemd project isn't also making their job easier by constantly adding new things and gently pushing distributions to use them.
