I don't see how this is any better than rate limits on the sending
side. It's not like a spammer will need to store 10000000 copies of
the same message to send it to 100000000 recipients, if they use their
own server. Likely public servers would perform de-duplication also.
And if they don't, it's not really different to the server just
applying rate limits.

Maybe there's an argument that server admins wouldn't bother to set
rate limits, but they would if every message cost them storage space.
On the other hand, storage space hardly costs anything nowadays. I
just don't see the benefits of this approach. Am I missing something?
