civix doesn't add urls to info.xml

Civix generated info.xml don't meet the requirements - I had to add this section to get it to upload as a release.

<urls>
<url desc="Main Extension Page">http://github.com/TechToThePeople/eu.tttp.excel</url>
<url desc="Documentation">http://github.com/TechToThePeople/eu.tttp.excel</url>
<url desc="Support">http://forum.civicrm.org</url><url desc="Licensing">http://civicrm.org/licensing</url>
</urls>

A couple of quasi-related thoughts / nice to haves if it makes sense to look at while delving into civix
1) when I run phpstorm inspect code on civix generated shells I get a few things highlighted like invalid return statements & things. Would be nice if these weren't there as it would encourage better use of IDEs
2) I add a versionAtLeast function to all my extensions to deal with interversion changes - should something like this be in civix / core?

/**

• is version of at least the version provided
  *
• @param number $version
• @return boolean
  */
  function _versionAtLeast($version) {
  $codeVersion = explode('.', CRM_Utils_System::version());
  if (version_compare($codeVersion[0] . '.' . $codeVersion[1], $version) >= 0) { return TRUE; }

  return FALSE;
  }
