Also emulation is a double edge sword too. In that maybe something is saved but another version will never be saved because it is 'already in the pack'. Yet that version had some cool quirk or bug fix. Getting OG stuff is challenging sometimes.

Recently I saw wince went EoL. If someone were to say to me 'we preserved your wince project' I would think that is not a worthwhile effort (but hey if thats what you want to spend your time on ...) . That software is not worth preserving. I even affected about 50k peoples lives with it. I would vote it is never preserved. There are probably thousands of projects like that. Where tons of people were affected by it and thousands of people worked on it. But the software itself is just not that worthwhile to save.
