I agree with you but I think the distinction made on udev and systemd is
that their *upstreams* didn't suggest they go in /usr. I don't know for
sure since I don't follow systemd and frankly detest it, but if they
said systemd and udev belong in /bin or somesuch, then they can't be
held responsible. The responsibility for that decision falls on the
maintainers, but it's compounded by the dependencies of systemd/udev.
They depend on dbus, which resides in /usr. Was that an upstream
decision or a distro decision? If we follow this dependency tree of /usr
moves, which package was the first to migrate to /usr and begin this
problem? The move to /usr was a social one that started years ago, not a
technical decision made this year. The issue right now is damage control
and, for some, maybe taking a good look at the FHS and deciding what
really makes sense.
