Public domain sprites?

[Sketchasaurus]

I always imagined that TSR was more of a library of sprites from completed and released games; the amount of quality control that is already done with submissions of ripped and customs already requires a lot of effort and if a public domain section is opened, it could potentially create more work for the admins. Now, if someone were to commercially release a game and wanted to upload the assets to TSR, I imagine that it'd be acceptable? (It'd be rare, but it'd be rather generous and useful if that sort of thing were to happen)
