So is it the reduction in tire deflection that reduces heat generation when going to a wider tire, or are people reducing inflation pressure to get the same amount of deflection but more usable surface area? Since getting that larger surface area on a smaller tire could result in uneven wear and strange feel because the tire is underinflated?

The engineering side of you is coming out again.
The interaction between cornering force causing deflection, sidewall resistance, how the tire pressure supports the sidewall, etc all play together.
I can go on for hours....
In short, stretched = better response, higher risk of debeading, and possibly larger contact patch (with proper setup)
