I knew I read something was kept for 6 months ;)

Glad to see that even here, the best way to get the right answer on the internet is to provide a wrong one.

IIRC, I've read comments elsewhere that pictrs caches for 6 months, but I can't independently verify. I hope this gets a broader answer because I'm still on the fence about getting an instance set up for myself and some small communities.
