[Openid-specs-ab] SSE & ChatGPT

Hey

I'm hacking together a PoC for OP Commands -- I'm a strong believer in
hands-on experience implementing a protocol, and I wanted to see if I could
find any issues with SSE. One addition I'll be adding to the doc is an
"error" event for when the RP has an unrecoverable error while sending the
stream.

Anyway, I came across this library that enables a nodejs server to be an
SSE client:

https://www.npmjs.com/package/eventsource

and was surprised to see it has >5M weekly downloads. Looking at the
dependencies, lots are ChatGPT related libraries. This makes sense as an
LLM response often takes seconds, and is a stream. It also is a similar
pattern to the proposal for how OP Commands would use SSE.
