If a fully quantum category will be found, and showed to have more than one model, then I think that the idea of reality as an infinite-dimensional configuration space inhabited by an atemporal wave-function should be abandoned.

Why?

Because then any model of the full quantum category would describe the same reality: instead of the infinite-dimensional Hilbert space you could just choose say a much looser ontology with sets and relations between them (as in Spekken's toy model of quantum physics).
This arbitrariness would undermine the raison d'etre of the present model.
