There is usually a significant period after the feature is stable but before the prefix-less option is defined or broadly implemented, isn't there?

Nobody is pretending that.  I think you might be reacting to a strawman "give up on prefixes and only have the option of saying 'I don't care if it's prefixed or not, give me the feature".  I think he's asking for that latter *as an additional option*, in the case where he's reasonably confident that anyone implementing the feature, prefixed or not, will give him what he wants.  For features with widely varying implementations, you wouldn't use this "any implementation is fine" syntax.
