The way I see OpenRaster is more like a toolkit to build raster file format. 
But as far as, Open Raster (long-term) Archiving is concerned, only the core 
functionnality are allowed, and for extension (like filters not available in 
the core), then providing a rendered version of the filter will be 
*mandatory*.

That said, I have started a list of filters I would like to see in 
version "1.0" of core filters : 
http://create.freedesktop.org/wiki/index.php/OpenRaster/Effects_Specification 
(it's mostly the list of SVG filters plus a few addition).

But I would love to see those buffer standardized as well (even if they are 
not part of ORA). I am pretty sure users would want to import GEGL-variant 
OpenRaster files in Krita as well (and possibelly the other way arround too), 
even if it's not the preferred way for interoperability.
