In my comments I look at what was gained and lost in the move from the Simple Thermometer Model (STM) to the Idealized Thermometer Model (ITM). The move is motivated by the thought that there are going to be cases of disagreement for which the simple model cannot generate results. In this way, the STM is incomplete. I try to say a bit about why we might think that the ITM is incomplete in a relevantly similar way, while also taking a hit in terms of its explanatory value. The STM tells us what to believe (even if not in every case). The ITM might be able to churn out results in some cases that the STM cannot, but offers less guidance about what we ought to believe.
