Interesting, I know personally one of my concerns with self-hosting an individual Lemmy instance (after losing my first account to the Vlemmy.net shutdown) was the threat of being held legally responsible for things cached on the server. Say someone uploads something illegal and my server caches it. Seeing it as an option to turn that off is nice, and for an instance only meant to be used by one person I’d imagine caching won’t have a huge impact on load times
