This is not the complete picture. The 'core' document of the annotation wg is the model document. That document defines the annotation objects in JSON(-LD) without explicit reference to RDF and formal RDF vocabulary. The 'vocab' document, that you looked at, is "only" the translation of that model to formal RDF. The exit criteria for the former are in:

https://www.w3.org/TR/annotation-model/#candidate-recommendation-exit-criteria <https://www.w3.org/TR/annotation-model/#candidate-recommendation-exit-criteria>

Another relevant comparison may be the _proposed_ exit criteria for DPUB-ARIA. That spec defines a vocabulary (not in the RDF sense, but for the ARIA role attribute); here is the proposed criteria:
