Automatic feature generation

[hylkevds]

In v1.1, when an Observation is created without a specific Feature, a Feature is automatically added to the Observation, and created if needed.
Do we still want that behaviour in v2.0 for the proximateFeatureOfInterest relation?

Given that we now have two relations to Feature, it may become hard to specify a way of automatic Feature creation that always works as expected...
In many cases the Observation will not have a proximateFeatureOfInterest, and the FoI for the Observation can be found through the ultimateFeatureOfInterest relation on the Datastream.

We should use some use cases to validate that we don't need the automatic feature_of_interest generation anymore?
