I don’t see the need for disk images. Most of the floppies had no extra information than the files themselves. Most did not even have a disk label. For the early AGI floppies with the CPC protection, the fake bad sector is not imagable.
That said, I do archive my floppies, too. I try to collect as many variations as possible. This is important for my installers. By far, the main reason that my installers fail is because the user has a version if the game that is different enough in content or layout that the installer cannot find all of the files to install. 5.25″ disks can have the resource file split into smaller and more parts. Some versions can have additional patch files, or even have main resource file repacked with a different map file. I can build in support for all of these other versions, but I need to have access to the media to add it.
