Square brackets in query component

The query production in 2396bis allows slash ("/"), question mark ("?"),
colon (":") and the commercial at-sign ("@") in order to improve
readability of URIs that appear in a query. However, square brackets
("[" and "]") are disallowed, which forces percent encoding in URIs with
IPv6 addresses. Can square brackets be safely added to the query
production?
