Comment (by westi):

 I think dots are a good addition see #15831 but I'm not sure about "-"
 because we don't support it in usernames.

 I think we should add support for "." and ensure we have the filters
 available for someone to extend the support for both usernames and
 hostnames to include - or other chars if they want.
