I don't believe they exist at the moment, I think all applets that use an 
extender are currently popupApplets (or the internal extender applet), so 
popupapplet could handle setting the correct margins etc. I agree that that 
would probably be sufficient (at least for a while).
That still keeps the question on how to approach setting the correct margins 
in PopupApplet when the extender is displayed inside the applet. The margins 
contained in the panelSvg leave a gap between the borders of the extenderItem 
and the border of the applet background, setting the margin to 0 makes the 
borders of the extenderItem stick out of the applet border. Either way, the 
extenderItem's background doesn't align with applet background properly. So 
should we add 4 elements to the applet background to indicate the correct 
margins for using extenders? Even PopupApplet needs to get this information 
from somewhere.
