qdstat text output is difficult to manage after a cut and paste. For instance, qdstat -l shows some rows where the columns are blank. This makes it difficult to reconstruct the original display given just the body text. See qdstat -l example in https://raw.githubusercontent.com/apache/qpid-dispatch/master/docs/books/user-guide/monitoring-using-qdstat.adoc
Even having a two-word column title "conn id" adds confusion.
With a CSV format and quoted strings this table could be communicated through email, chat, or Jira with authority. Readers would not have to guess about which data goes in which columns.
