The key here is the work of the Holy Spirit. It is he who hovers over the chaos and brings about order.    It is the job of the Holy Spirit to lead the church - with our help and cooperation.  Even Jesus, (yes, Jesus, God incarnate) was led by the Spirit.  

If the Holy Father believed that having more  "clarity of expression" would better serve his Lord, he would do it.  There is a higher spiritual purpose behind his way of doing things.   He is not against the questioning or critiquing or even disagreement with what he says.  He has said this on several occasions.  He wants honest dialogue and seeking of the truth and integrity in church teachings.   "Polarization" is an 'us versus them' attitude and "animosity" is about  uncivil, hateful, accusatory attacks. This correctly describes the Holy Father' s enemies and such are not the fruits of the Holy Spirit.

"...expert theological reflection."?  What about the lived and gut-wrenching experiences of the children of God?
