[Openid-specs-ab] OpenID Provider Commands - proposed WG specification

Sun Feb 16 01:01:45 UTC 2025

Hi Dick,

I love this idea as it simplifies a ton of things. Starting from the first
one - having Shared Signals (RISC) and SCIM are not necessary to meet most
of my requirements (I am interested in changing account statuses and
account deprovisioning). Yes... There is a huge overlap between OP Commands
and these too, but I am not going to touch on this topic.

One thing that is not particularly clear for me is your concept of streaming
requests and responses from an OP to an RP using SSE (Server-Sent Event).
To the best of my knowledge, once an HTTP client starts an SSE connection
and sends the very first OP Command to the server, it cannot send any
additional HTTP requests (or OP Commands in our case). It can only listen for
responses from or close the connection. How will this work unless you allow
sending multiple OP Commands (we know that's easily possible with x-www-fo
rm-urlencoded)?

All the best,

Andrii
