Úgy vélem, hogy tévedsz; nekem az a benyomásom, hogy a W3C ajánlása pontosan a minimálisan támogatandó codec-eket akarja előírni (többek között) -- vagy legalábbis akarta.

The HTML 5 video element has the potential to liberate streaming Internet video from plugin prison, but a debate over which codec to define in the standard is threatening to derail the effort.

I have therefore removed the two subsections in the HTML5 spec in which codecs would have been required

Sadly, even if the spec does require something, it's no guarantee that it'll remain implemented. The spec doesn't force browsers to do anything. Implementors only do the parts they want to do.
