That seems reasonable to me, too, although I am somewhat more sanguine about the stability of image formats. In 1992 I wrote a book called Graphics File Formats, and almost without exception the formats we described in that book are handled by all of the image tools that people use today, including GIF, TIFF, PCX, JPEG, and BMP. If we pick a small set of well-known formats, it'll be decades before anyone has any trouble reading them. Indeed, the hardest part of implementing Paul's proposal will be to maintain the institutional memory that the RFC Editor is supposed to do format translation if the formats go stale.
