Agree. Previous community developed codecs have involved a period of time
where the specification is considered experimental, before being frozen.
The experimental phase provides an opportunity for developers & users to

Great. If nothing has been decided yet, please revise the website text
that states 'The VP8 and WebM specifications as released on May 19th,
2010 are final.'
