As far as I know, aggr.nostr.land does plan to implement the outbox model, but it doesn’t seem to be finished yet. Once it is, I’d be happy to support it — that would significantly reduce performance overhead.

I suppose YMMV but it works well as a proxy in my personal testing so far. nostr:nprofile1qqs99d9qw67th0wr5xh05de4s9k0wjvnkxudkgptq8yg83vtulad30gpz9mhxue69uhkummnw3ezumrpdejz7qgkwaehxw309askwemj9ehx7um5wghxcctwvshsz9thwden5te0wfjkccte9ejxzmt4wvhxjme0e68ksk what is the status?
The goal is that for broadcasts it will use outbox. For receiving, it scrapes all relays so that should be a solved problem.
But I am intending to add a proxy mode where it can AUTH proxy as well
