Hello all, on one hand, I understand the need for interoperability and therefore avoid non-interoperable solutions, obviously. On the other hand, I would strongly recommend to allow for non-YANG-molded data here. Over the years we have seen a lot of convergence wrt to endpoint-, network- and function- visualization. While this might sound like the first sentence of yet another boring ivory tower publication - it is a fact that for multiple reasons code bases merge to simply onboarding, enrollment, deploylmen and maintenance of network equipment. Using YANG-based interfaces to support this ongoing convergence by allowing for non-YANG-modled data is considered vital by a multitude of stakeholders. And while it is of course more difficult to enable interoperable implementations in this regard, it seems to me due to the fact how the "YANG-part" is structured/modled today it is neither harmful nor useless to the internet - and in contrast very useful to migrate away from older legacy interface. I am new to the domain of NETCONF, but I am in strong support of allowing for non-YANG-defined notification messages wrt migration, simplification of implementation and well... simply moving away from a zoo of procedures that are already a nightmare. This is a chance get rid of that existing "nightmare" step-by-step and provide a path forward to enable structural and semantic convergence of data conveyed. This is why I care very much about non-YANG-modeled telemetry provided by a YANG-based interface.
