I think it's better to include Parse and Bind as now.  Parse or Bind could take long time when the table has many
partitions,the query is complex and/or very long, some DDL statement is running against a target table, or the system
loadis high.
 

Firing statement timeout during or after many Parses is not a problem, because the first Parse started running some
statementand it's not finished.  Plus, Andres confirmed that major client drivers don't use such a pattern.  There may
bean odd behavior purely from the perspective of E.Q.P, that's a compromise, which Andres meant by "not perfect but."
