Long-term report: The NM applet within the Xfce panel still is ok. I expect to get issues from time to time using NM, but until now even those didn't happen. Again, no systemd ;).
OT: Btw. it would be nice if everybody has got the choice to use or not to use systemd. IMO there's no need to talk about pros and cons, Poettering again and again. I suspect we use different mail clients, daemons etc. too.
