No, it's not just that: it's that these filters don't fit the vision of a
high-end painting application. Emboss has useful properties, which is probably
why Cyrille put a question mark next to them. Raindrops and oilpaint would be much 
nicer if implemented as brushes instead of filters, probably as part of the
deform brush. That way, the result will be dependent upon the artistic skill
of the user and different from artist to artist instead of mostly similar.

The 1.6 watercolor color model was a direct port of Wet Dream, giving much the
same result.

That's the case for most of these academics. There are also interesting papers
on www.billbaxter.com, and there's Tom van Laerhoven's work. But nobody
publishes source code!
