-no-frame was deemed to be a SDL feature that was unnecessary for GTK, hence dropped. 
At run-time, it is checked whether -no-frame makes sense or not (that is, if `-display sdl` 
was specified or not). Original patch and discussion can be found at 
http://lists.nongnu.org/archive/html/qemu-devel/2013-06/msg01297.html.

As for the discussion about legacy options[1], are there plans to remove `-sdl` (replaced by 
`-display sdl`) and move the `-*-grab` and `-no-frame` to `-display sdl` options? If that is 
the idea, what about printing a message that the mentioned options are deprecated and 
removed in a future version?

Regards,
Peter
