I don't really think it is necessary to summarize. A lot of things will be missed if someone only reads the summary. But whoever wants to write a summary of their reasonings is welcome to.
And as far as concluding our topics, this might be hard to do, because people don't always agree after the reasoning is finished, so a conclusion never came. And also, if the reasonings are left open, then old reasonings can be brought to the front again if someone thinks of something to add to the reasoning.
