Well, technically StumpWM doesn't and cannot meaningfully support the 
feature in the default mode, because it is supposed to choose whether 
the window is borderless, and in StumpWM there is no choice.

Is the problem just a warning printed or is some behaviour wrong, too?

StumpWM can be asked to behave differently (with window borders and 
overlapping windows and such) for a separate virtual workspace (group);
but that's not what you are asking about. In that mode, asking for 
a borderless window would make sense. feh still seems to get a true 
fullscreen window.
