I thoroughly agree about the event-based-computing model but telemetry (as per the current common definition) won't drive this far enough. We need to take the telemetry model one step further and have the easy facility to insert shims at set levels (e.g. between the business layer and the data store) with open auth to be able to insert subscribers in an open manner to the entire payload. This should then be mandated by any org implementing a product and especially any gov org to prevent vendor lockin and allow easy extensibility. Same concept, but more data.
