Consensus? Probably not. Theory of the value of it's application.... yeah.........

It's really not necessary for most aerobatic models. They're usually designed to be as neutral as possible. Not to have an UP or DOWN preference. They've got symmetrical wings for example, and aileron differential is mostly used to help dihedral winged airplanes with cambered airfoils. As you move from those types to the neutral ones, the need for differential lessens to zero.

All the Caps, Extras, etc I've had benefitted from a bit of mixing to tone down the rudder couples, but I've never had one need aileron differential. They all had symmetrical profiles however.

Personally, I've never put a mix into the radio for adverse yaw from the above reasons, but will trim with the radio in a heartbeat to tone down rudder couple. And that's probably because of the types of models and how I use them. It just seems appropriate to do it that way.
