Hassio homeassistant restart output

With the upgrade to 61.1 I now have this result after a command line restart…

config hassio homeassistant restart
{
   "result": "ok",
   "data": {}
}

This is new, any reason for the change to json output?

Also, why does hassio homeassistant restart auto complete to hassio home-assistant restart which does not work. The dash does not belong in there.
