shouldnt there be a public annoncement about the intend to make the API public
shouldnt there be a public call for API design suggestions and discussion
shouldnt there be a public call for API related patches with deadline
shouldnt there be a go/no-go poll of the FFmpeg developers

I dont think a wait period makes sense. By the time everyone is ok
with making the API public the code will have been more then
extensivly tested and waiting further would likely add little
