Predictivity conjecture for effective quantum general relativity

Let an effective quantum field theory consist of Quantum General Relativity, possibly coupled to matter from the Standard Model. A theory is predictive when its coupling constant set is finite and either its counterterm set is finite or its quantum gauge symmetries induce a finite set of counterterms.

Predictivity conjecture. (Effective) Quantum General Relativity, possibly coupled to matter from the Standard Model, is predictive.

This claim extends the usual classification by renormalizability and is motivated by constructions of quantum gauge symmetries and counterterms for quantum general relativity. The source presents it as a claim, but the supplied text gives no resolution status.
