The most important aspect is to save/conserve the equipment and knowledge so it would be possible for somebody else to take over. Something like this happened with Polaroid - a group of enthusiasts got Polaroid equipment and managed to partially restore the development of Polaroid integral instant film (the one where everything is packed into single package). Unfortunately the much more beautiful and photo like "peel apart" instant film was already scraped by both Polaroid and Fuji. I would even consider this a cultural vandalism, similar to destroying important cultural artifacts.
