  Luke, please be careful with quantificators like ”any upstream developer”.
I invite you to check sd_notify() and/or socket activation that I did* in
various projects: rrd_cached, iscsid, transmissionbt, owfs, uptimed, tor.
  In each case there is no degradation when systemd is not used, previous
way of doing things is preserved.  Enhancement patches (Type=notify, watchdog)
are NOOP when systemd is not used.  Some of the above project don't even
lin with libsystemd.

* in case of Tor and transsmission I've either inspired the change or expanded
  it over original patches; for others I prepared a patch which was merged
  by upstream
