Retract scapula for which exercises?

[Soloshino]

Apart from flat and incline benching (DB & BB), are there any exercises where not retracting the scapula would limit engagement of the primary muscle the exercise is designed to target?

DB flyes for chest. If you lift your shoulders slightly at the very end of the concentric you can get a more complete pec contraction
Edit: I misread your post. What I meant was retracting the shoulders would actually limit your range of motion and the force of the contraction.

Also I believe as long as you're feeling the correct muscle work you don't have to religiously follow all the so called "rules" for lifting. Every body is built different. Forcing your body into a position that is uncomfortable is part of why people get injured.
