Randy: We feel that we are victim of this discussion with confusing title. I don’t want to comment on whether the intent is right or it is time for intent or not, you have your judgement, but: 1. The liaison is sent to NMRG instead of this WG since they believe the more relevant work is over there. (https://datatracker.ietf.org/liaison/1724/) 2. The intent in different context means different things, intent translation, intent mapping, combining with AL/ML is not in the scope of this work. 3. The ECA model borrows similar concept from RMON which is successfully specified by IETF, ROMN is extension of SNMP, provides traffic flow data for troubleshooting and provides the control to adjust for better performance. So why not ECA 4. ECA is abstracted from bottom up and use telemetry protocol as a good basis and provide a clear semantics which is different from intent you quoted from elsewhere.

I vividly remember an X3T5.4 meeting in which we *thought* we were wrapping things up, until someone (me) foolishly drew an E-R diagram on the whiteboard, causing us to realize that although we thought we had reached agreement, we had in fact been using the same words strung together in the same order to talk about radically different models.
