That is true, but the proposal here was for introducing a general mechanism for grouping observations, with the latest-value-slice just being one example.

Subclasses of qb:ObservationGroup with more precise semantics could be defined in extensions.

Ok. This would be a superproperty of qb:slice, I presume.
