do you even know it’s there? would you be sad to see it go?
personally i’m not particularly fond of it because of (mostly insignificant unless you share your tt-rss instance with strangers, but still) possible privacy issues. plus, i think it’s kinda useless in general.
additionally, while feed archive might have its uses, i’m not sure its the best idea to keep (indefinitely, by default) feeds that were unsubscribed by users.
i don’t plan to remove it but maybe there should be some automatic expiration involved there.
