I doubt anyone with a package in contrib wants to keep it there, no matter what their position on non-free is. Having no packages that're worth maintaining in contrib would be a strong argument that non-free software isn't necessary anymore, IMO.
Looking at contrib, I see the following major groups:1. Java programs. It seems that work is happening to make some depend on free java-like systems, but more help would be welcome. 2. Emulators. They're mostly contrib because their ROMs are non-free. Difficult to move. There are some which looked moveable, but I've not checked in detail. 3. Enhancements and front-ends for non-free software. qmail scripts, for example. I think most already have replacements in main. Are there ones which aren't redundant? Could they be ported to software in main? 4. Free software data files for non-free software. Do these really depend on non-free? I guess they may be pretty uninteresting without it. 5. Installers for non-free software. I can't see how these can ever vanish unless their maintainer accepts that an alternative exists in main and it dies that way. 6. Free software with non-free essential data. More general case of 2 which probably needs upstream convincing or the data replacing with some under a free software licence. 7. Free software using a non-free essential library. Probably a more general case of 1, which needs it porting to use a different library, or that library part made optional and disabled in the debian build. I was surprised there were so few of these that aren't java.
I actually stepped through a 30% section of the contrib list and then did a sample of the remainder, so I may have missed a class or more. Can you spot it?
I think there are 254 packages in contrib (grep -c '^Package: ' Packages). If we want to reduce the size of contrib, I suggest classifying these and doing something similar to my previously posted plan for reducing the size of non-free. Is anyone interested in doing this?
