[@mention:532592670943008396] To your question "What would be lacking without Reaction Round?", I would say many things. One is a safe space for people to digest the proposal - some of us need to speak loudly to reflect on something. Another one is a safe space again for people who may feel some pressure, kind like some attachment to the proposal, to express the inner pressure they feel. Another purpose which is my favorite, is to help the Proposer by modeling/offering different pathways that may address the Proposer's Tension. And I'm sure they are more into it. 

Hello Jean-Marie and thank you for your contribution

I understand better the first two added values that you mention (safe space to digest the proposal and to express the inner pressure some people may feel.)

The added value that you prefer (to help the Propose by modeling / offering different pathways) is the one that I also prioritized.

In reading these answers, I come to the conclusion that according to the vision of each, the prioritization varies (the purpose of the reaction turn is for some to digest the proposal rather than discovering different pathways and for others of which I to discover different pathways rather than to digest the proposal).
Obviously, both purposes are active in practice.
