I didn't think so, and I gave the definition *I* use.  Sorry if I implied
otherwise!

(My last sentence was in reference to Helmut writing "[...] I still don't use
systemd as my init system.[...]", which I thought was a bit of a silly
formulation, given his question :) .)

Which is where my second paragraph came in, pointing out that - and I'm
repeating myself here - that, to my understanding, it's not so much that upower
needs systemd, it's that it expects systemd to take over functionality that
upower used to provide via pm-utils (hibernation, etc.).  So it's a *runtime*
problem: if you boot with systemd, you should use plain upower, if not, it
depends on whether you need the functionality provided by pm-utils (which only
the user of a system can know).

Again, this is what I gathered from the previous looong upower discussion. You
*can* use the newer upower without systemd, but you'll be missing functionality
it used to provide via pm-utils (which is pretty much what Tom Wijsman said in
one message).
