Why rate-limit ephemeral events?
They should be limited only if it starts taking serious amount of bandwidth.
I think ephemeral events are great if you have something like a cloud-function that runs once in a while and needs to send requests to some computer behind NAT.
Every event will be ip-rate limited on public relays, by all means use whatever policy you want in your own relays
I understand, but can we agree that ephemeral events could have much higher limit than normal events, since there is no need to store ephemeral events?
A successful website with some backend in a home computer behind NAT might even start paying to the relays when the number of visitors increases.
