Ah, just noticed ancient https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=377056

For some reason i thought that XSS not only had it, but also was the first one to implement it. But it seems that its developer isn't too keen on this new "kit & bus" fashion.
So now one has to use those abominations just to have a screensaver ? Then `xdg-screensaver` abstraction should have, probably, been used instead of direct dbus calls. It supports both dbus and console commands.

Otherwise https://launchpad.net/caffeine shim is the only cross-DE option, it seems.
