We have to keep the spec from running away from implementations anyway, whether we have a stable snapshot model or a continually evolving model. > After a spec gets to CR it can't just mutate out of thin air, hence > forking it into a new version is the way to go. > > Example: Gecko, Webkit and IE have localStorage, but the spec changed a > few days ago to allow structured storage. If we do snapshots, it just means the implementors are working on an obsolete version of the spec, which is worse. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
