Well, systemd is an alternative to openrc, and I like it too.
No offense, but in my opinion, since systemd is still in-tree, then there should be some basic support for it. Otherwise, just remove it from portage tree. This is quite reasonable.
Another reason for systemd support: I want to have a bit taste on gnome 3.14 over wayland (but I do not like Arch or other distros). However, wayland requires systemd as its dependency.
Of course, if funtoo devs could remove systemd dependency from wayland, then I will happily stay with openrc.
