Why should the author work around Signal's rate limiting? Are you asking the author to enable spamming?

[DaSHacka]

GP is presumably asking what their plans are once the service gets popular, runs into the ratelinit, and cannot send any notifications at all (or with significant delays) to the clients.

Messaging is internally rate limited and capped per recipient. And it uses a sender pool.

I use per-recipient internal rate limiting too, that alone is not enough, especially for new numbers. I'm not using a sender pool though.
