Yes, I haven't looked closer on how to handle dependencies to tmpfiles. 
Maybe that is tricky. Maybe you're better off writing a setup-service 
that your service can depend on (maybe that setup service even could use 
systemd-tmpfiles to create the files). But I know Fedora is using 
tmpfiles to setup prerequisite directories.
