I'm speaking up! Before accepting a proposal, we should be content that the proposal itself stands by itself. Our protocol says that we'll push back (promptly) to "Please revise", in the constructive spirit of "we are going to accept this but want you to make the proposal clear first".
This is not a big deal -- we are going to accept it! But I don’t want accept until the proposal is done.
Simon
