This sort of thing is apparently the reason for how long it took for Adobe to provide raw support for the pretty neat little Panasonic DMC-LX3. Panasonic were apparently insisting that no raw conversion would have their approval unless it incorporated correction of geometric distortions (said correction having already been built into the camera's jpeg creation, and into the painful-to-use Silkypix raw converter Panasonic provided). Users clamored for Adobe to just release a straightforward conversion, which people could fix afterward with the magical barrel/pincushion slider, so everyone could use their accustomed Adobe tools; but rumor has it there was such iron insistence from Panasonic that a company which allowed people to see the uncorrected images from that lens was no friend of theirs, that support for the camera had to wait for a new revision of Adobe's whole raw-processing pipeline which incorporated the notion of per-device image corrections which had to be applied before something came out the other side. -Jeff
