I mentioned it in the post, but yeah, also not trivial.

Polling /events solves some problems but introduces others. A mix of push (webhooks) and pull (/events) can also work, which is what I was referring to with the "thin clients", though it's not a great experience for many use-cases and it requires state (many webhooks recipients are stateless - e.g Zapier or Slack).
