[vlc-devel] [PATCH 1/4] libvlc: Add "fullscreen-monitor" setting

As noted in the last or previous to last video workshop, the whole point of separating open and enable in window provider was to support this - just like why I split open and start in audio outputs earlier.
And with that, I totally disagree with your proposal to essentially regress the design.
