Yes, indeed.

The smart implementation on VLC part would be falling back on SR checks 
for liveness if the server does not respond to GET_PARAMETER.
I will try to file a bug, but I bet I'll have an hard time, because 
formally VLC developers are right (if the option is listed, VLC has the 
right to use it), even if it's a brain-dead schema.
