I think the only major event generator we're interested in is the Almighty :-)
A VOEvent packet is a report alerting the community to an event that has occurred in the sky.

VOEvent already supports both points of view. A time series can be constructed internal to a packet using the param mechanism (this is one of the examples in the spec) - or a time series can be constructed externally as a thread of follow-up packets. For v2.0 we are seeking to improve the internal mechanism.
Perhaps we will also discover some desirable improvements related to time domain follow-ups. Most of our follow-up use cases have been rather ad hoc in nature - target of opportunity observing modes, for instance. Are there any aspects of issuing a rapid sequence of several related, sequentially timestamped, packets that we need to explore and enhance? Do we think this will represent a significant fraction of the usage? After all, one key concept is to traverse a thread of follow-up packets and abstract the evolving behavior of the source(s) and related (and perhaps only inferred) celestial object(s).
