That's "quite obviously" an after-the-fact justification and the
corresponding freedesktop.org text,

http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken/

(still) quite plainly states that udev (it names no other examples) is
developed based on the assumption that / and /usr reside on the same
device and that any bug reports regarding this are WONTFIXes. IOW,
that's a policy decision certain people originally made for "their
systems" which is now forced on everybody else.
