Sorry - I didn't write that correctly. It's already very powerful for making bitmaps (I've only got a 1.X version but use it for that purpose). And the iconset example was a bad one to give. I'm interested in AWRender because I can't justify purchasing AW 2.X (not a serious enough user TBH,) but do use AW files a fair bit.
The obvious reason for my suggestion is if you don't need to create Artworks files with transparency, but you do want to manipulate existing files in other formats - say using them as pre-sized images in other products which don't support Artworks formats. Currently even non-Artworks users can create sprites from them with a screengrab with Paint. To create sprites from Artworks files with transparency would require buying the full Artworks 2 package (or make sure your final background is white...)
If you're contemplating a chargeable AWRender package, a feature such as this might therefore be more useful to more people than in Artworks as a whole.
Of course, since the code would be near-enough identical, it could always be done both ways . Anyway, just a suggestion.
