Review comment:
Yes, it's a somewhat quirky behaviour. Operationally it could also cause
mysteries e.g. when new features are added to an existing store and the
(reasonable) expectation is that they will start producing feature values right
away when actually that only happens when the existing model(s) are next
re-instantiated. +1 to try and reduce such confusion via documentation somehow.
