Currently `create` events offer no explicit indication of the type of the namespace that’s been created. Clients have to parse it heuristically:

1. If there’s a collection UUID: type=collection.
2. Otherwise, if viewOn is a system.buckets collection: type=timeseries.
3. Otherwise, type=view.

This means clients have to know about all collection types. So were there to be some new collection type, the logic above would process it as a view. Moreover, a client that doesn’t want to care about time-series collections nonetheless has to filter them out explicitly.

It would seem better all around to add a “type” field to the event.
