That’s really useful to know, thank you!
I guess my followup question then is: can you deliberately cache some entries?
Also, how easy would it be to override which of your peers you asked for the lookup?
For context, my use case is a social network. I’d like friends to be peers when online and cache each other’s IPNS entries (ID -> profile-hash). On updates to your profile you send the new IPNS entry to your friends, they update their records, and then hopefully lookup done by another friend is fast. So recency does matter as well here.
