Nice.  It took 5 minutes to rebuild my OpenSCAD filter as plugin module 
(without changing single line in my sources) and it seems it works...

Is this possibility documented somewhere? I knew about plugins, but I 
did not know it works for exporters too...

Just curious why nobody mentioned this possibility before... it would 
simplify lot of things.
